I have always thought that the amperage of a battery made no difference to the voltage due to the factory adjusting the internal resistance of the battery. Amperage I understood was measured in current, however, which does have an effect on overall voltage.
Recall:
V = I * R
With electronics, it is my understanding that the mAh battery doesn't matter as long as the voltage is the same, although you'd get less longevity out of a 1650 mAh vs a 1440 mAh.
Thus, I believe this battery would work. Thoughts? The part number matches exactly what was in my Nexus S and the batteries look identical. If this is the case, save yourself some money buy not searching Nexus S battery and instead searching ab653850ca in eBay instead of paying $30-$40 for a new/replacement Nexus S battery when they are the same thing.

Thoughts? Both are 3.7 volts.
mAh is a unit of electric charge, not current (notice the 'h' making it milli-Ampere-hour). So, yes, a lower mAh battery will definitely work, but it will last less time.
Also (just trying to explain better) a battery is not a "powered resistor", so the relationship between its voltage and its current is not just ohm's law (the one you recall). More specifically, the 3.7 volts is due to the chemical reaction inside the battery and is more or less fixed (although it decreases as the battery discharges). The current flowing is basically a function of the load of the battery, so it changes according to what parts of the phone are working at that moment. The output resistance of the battery is a formal way of describing how close the battery is to an ideal voltage source and is not related to the amount of current it's actually providing.
Sorry if I was not clear enough, it's late here!
Missed the h. Not sure why, I see mA all the time and I just missed the h. Interesting and helpful. Thanks man. Clear to me.
That's strange, if it is the same model (AB653850CA), why is it only 1440mAh? But I'm sure it will work.
All I know is that this Samsung Moment battery I got off of Amazon for $6 is almost as good as my stock battery.

The 1440mAh batteries work perfect, I have 2 of them. While you are at it, buy a wall charger to charge them in so they will charge to 100%. Having 2 spares means you will always have a FULLY charged battery to pop in and never have to tether the phone to a charger. Plus you get 2 to 4 extra hours of use.
Very informative!

What do you mean by that ? That the 1440 mAh battery only gives you 2-4 hours ? I doubt it lasts so little time. I hope it doesn't.
No he means charging the batteries in an external charger gives them a more complete charge as I find the same thing. I've got 2 genuine batteries and a third on the way and the external charger charges them to 100% whereas the phone only charges them to around 95%. The batteries charged in the external charger last longer than those charged in the phone.
Hard to know when you're legitimately getting a battery with "more capacity" though, so I just assume I'm always buying another stock battery anyways.

Oh, I got it, thanks !
Anyway, for 6$, I think I'm going to buy one, too. Coupled with the 2nd battery dock, it should work flawlessly.
Hey guys,
I went ahead and ordered one of these too. I noticed that the Watts/hour is 5.55 on the Nexus S battery but on the battery I ordered (but have yet to get in) it says 5.3. Is this going to make a difference outside of how long the battery lasts?
If you guys buy one of these 1440s report back with what you've found out.
And if this is a success, then please urge XDA to sticky this thread or put this on the main page. Paying $50 for a second/replacement Nexus S battery is outrageous, and if this saves my fellow XDA members $45, more people should know about this. :]
UPDATE:
Looks like turbodroid already ordered these and said they work great! Thanks guys! Thank me if this was helpful.
The design of the Streak seems like it could fairly easily take a back with a solar charger built in. Has anyone seen something like that?
Sent from my Dell Streak using XDA App
I think you would have difficulty finding a solar panel small enough with enough power output to do any good, not to mention having to leave it out in the heat of the sun while it charged.
Good point.
Buts not about replacing the mains charger but adding a little charge while out and about. Prob get a few days extra with solar panel. Unless you forget to take it out of your pocket
I think its a great idea. Maybe a battery with built in cover/solar panel
Sent from my Dell Streak using Tapatalk
does sounds like a good idea you can already get solar phone chargers but one attached to the phone would be great!!
you'd probably be better off looking for one of those solar power batteries that could charge an internal battery, then use it to charge the streak once the charge is up
Solar chargers work under indoor lighting also. My watch never dies on me and I'm indoors all the time. As long as you left the unit face down, it would trickle charge and maybe get enough extra time to never worry about dying out before you get home to your charger.

Problem is the Streak needs an awful lot more power than a watch. I see this panel on eBay http://www.ebay.com.au/itm/5V-150mA...895?pt=LH_DefaultDomain_0&hash=item4aacb1b777 which they say is 5v 150ma and it's 110mm x 56mm. This is roughly the size of the battery cover on the Streak, but you would need 7 times as much current to successfully charge it.

What if you combined this with the battery idea? So it would charge a second smaller battery, and when your battery was running low you flipped a switch to charge the streak from that? It would start to get bulky but might work?

I bought two extra charging cables. One for the car, one for work and the original stays at home by my computer. Charging problem solved with nothing to lug around. This thing is big enough without toting around accessories.

No you wouldn't, it would charge with only 150ma, it would just take about 10 hours for full charge, in reality, something like this would only slow battery drain on a "super"-phone like this.
That's my point - not to charge from dead, but to top up and maybe get an extra hour or more before searching for an outlet.

Aren't there serious problems with trying to trickle charge Lithium ION cells? As in, it kills them pretty quickly?
Isn't that why loads of modern kit has normal and fast charge modes, depending on what the available amperage on the cable is, and why some things, e.g. iPad, cannot charge at all from some USB ports?
As far as I know the only thing you don't want to do to a lithium battery is let it discharge fully, that shortens the battery life considerably.

This didn't make sense to me, so I Googled. It is correct. I found this quote on a battery research site.
"Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."
There was a chart that indicated that discharging only to 50% as opposed to until it dies can triple the battery life.
The moral is to have it on a charger whenever possible.
Well, according to http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety.

After reading that article, this statement I made previously is clearly wrong.
What I gathered from the article is that for max lifespan of the battery, a couple of things should be done:
1) Do not completely discharge.
2) Turn the phone off while charging.
Of course with the Streak it would be impractical to do both of these, as it would mean turning your phone off for an hour or so in the middle of the day.
Oh yeah, and hope like hell that Dell did a good job designing the charger circuitry.

If battery is around 40% it being be charged overnight.
Anyone else experience this?
could be the amp? maybe below 1 amp? Samsung charger has 2amps om it. check your charger and look for the amp. btw. the lower the amp the better for your battery..
Buy an OEM charger. The Samsung one is $50 from Samsung website but you can get the Asus charger from Google play store for $25. Both are two ampbi believe. Or you can get the 1a for $25 from samsung. Getting OEM directly from an OEM or authorized reseller or a storefront lime Google is key. Getting cheap chargers is gonna bite you in the ass one day or think about it like this. Why keep wasting time buying cheap chargers again and again when you can put up proper money and get quality in one go and have peace of mind for a few years. I even stopped buying chargers from amazon because they're just cheap knockoffs too. Phi hong makes good chargers and power supplies but they are harder to source. Phi hong came with my nexus one andy galaxy nexus OEM Home dock.
Anyways, aside from that part of the reason for slow charging is you probably have an unsafe charger that is not rated what it really is and is made of poor materials. Getting a quality 1a or higher, preferably 2a in this case and your gnote2 should charge @ 1.8a. In other words, you can charge from zero to full in ~2-2.5 hours. Or from partially full to 100% in less than 2 easily.

Unless I am mistaken, OP is referring to battery chargers, not usb chargers. That's how I charge mine, too. I have spare batteries, and they all get charged directly. When my battery is low, I just swap. I hate having my phone attached to a cord, even at night.
Yes, all the battery chargers I've had for every device (including this one) have been lower amp than the usb chargers supplied with the phone. It is especially slow for this huge battery for the Note 2. While it bothers me in concept, it's never actually been an issue for me, so I haven't done anything about it. I don't know if higher amp battery chargers are available, but I don't feel like spending extra money on one.
As far as battery health goes, charging at a lower amperage certainly isn't hurting the battery. If anything, it's actually better for it.
Yes...charging just the battery with wall charger.
@ 40% it will not be charged at 6am when I wake!!!
Are there better wall chargers?
Why do you hate having your phone attached to a Cord overnight. I heard that's fine and do it every night.!

Not for the phone, for me. It just bothers me having a wireless device locked to a wall. There's no reason for it. And I frequently get up in the night for various reasons (kids, work, insomnia, etc), and it bugs me unplugging in the middle of a charge cycle.
Incidentally, a non-removable battery was a deal breaker, and one of the reasons I didn't get a Nexus 4. I got used to never plugging in my last phone, and I don't want to go back. It was torture the first week or two with the N2 before my spare batteries arrived.
The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.
I'd be worried about my back cover getting loose doing what you do. I had three batteries for my old phone, but I did not swap them on a daily basis, just when travelling or away from power for an extended time. I've ordered some wireless chargers so I can have one by my bed and another downstairs. I know they only output 500mA too, but for an overnight charge thats fine for me. I dont think there is any issue with interrupting the charge cycle, the two main enemies of lithium batteries are heat and being totally/almost discharged on a regular basis. Its best to keep them topped up.

It looks like the OEM battery charger is available on ebay for around $15. That's good to know in case mine ever crap out on me. These cheapies that I get tend to.
As far as the back cover getting loose, after 3 months, it is a little bit looser than when it was new. 1.5 years with my G2x didn't loosen it at all, but the build quality on that thing was fantastic. I keep this in a case anyway, so it being a little looser goes unnoticed. If it gets bad, back cover replacements are cheap.
If one of the devs can make the kernel capable of fastcharge, it would not take but half the time to charge. Yank who is working with Faux on his kernel, helped make the kernel fast charge capable.

But what is the point of having it charge fast, when all it is is going to drain faster?
I charge mine overnight with a charger rated at 750mah I believe and it last me a whole day. As oppose to using a 2.1 am charger I have, where the battery percentage would start dropping by the first hour.
Correct me if I am wrong here, but this is what I've notice with my last few phones.
The Perseus kernel with stweaks has the ability to change the charging parameters.
With it overclocked/undervolted I am getting better life than I did on stock.
Not for sure what you mean as it depleting the charge faster on a higher amperage charger. Kind of sounds like you may have had failing batteries, etc.
There seem to be a few misunderstandings here regarding batteries and chargers.
1) The charge rate, when the battery is in the phone, is controlled BY the phone. The charger itself just supplies regulated power to the phone. How much current is put into the battery at any given time is up to the phone, which is why kernels can do things like fast charge, it's controlled by the kernel. Now, the reason the battery charges faster when using the stock charger vs. something lower current or a computer is simple. The phone can detect what it's connected to within some limitations. It sounds like our phone can also sense the incoming voltage levels and back off if the supply becomes unstable.
2) Using the stock 2A charger is "harder" on the battery than a lower current charger. Not true, at least not within any margin of error you will be able to detect without specialized equipment. Lipo batteries are generally built to charge/discharge at 1C. C in this case stands for capacity. So our 3100mah batteries can charge at 3.1Amp and be within safety margin. So the 2Amp charger the phone comes with is perfectly fine for the battery. Without seeing a datasheet for the battery from Samsung, that's a good guess. And again, the phone controls the charge current based on a number of parameters. You could connect the phone to a 5V supply capable of 100Amp and it will still only use what it needs.
3) The percentage readout on the phone screen is a GUESS. Don't pay it too much attention. For this same reason, evaluating 3rd party batteries based on phone runtime etc is not useful. To validate the battery capacity with any accuracy requires a test setup discharging the battery through a known load and measuring how long it takes to get to a cutoff voltage. I've done some of these tests myself on stock and 3rd party batteries. In general, the OEM batteries are always at or above spec, the 3rd party battery manufacturers lie. Often by upward of 20%. Even the high $ batteries. Keep that in mind when shopping if you want extras or extended batteries.
4) Interrupting the charge cycle is bad. Nope. It's fine. On this same line of thought, full cycles ARE bad. Don't do it. Don't think too much about it either though. Just plug it in when convenient. Or set it on the wireless charger if you've installed one. Generally speaking, they actually don't like to be charged to 100% either. Keeping it at 20%-80% is actually best for the longevity of the battery cell itself. In practice, you will probably have a new phone before any of this is actually noticeable.
The OP sounds like they are talking about a stand-alone charger, where the battery is not in the phone. Those will vary wildly in quality and capability, particularly from ebay. They are probably cheap POS devices. Not that that's really a bad thing, just know about it. It's probably a very low charge rate device, perhaps even down to 100ma or so. That would take forever to charge our larger batteries. As for if there is a better one, probably. If Samsung makes one, it will probably charge faster than the phone with the provided charger plug as there would be no load from the phone using power. Of course, it will cost a lot more as well. Look for devices that at least claim they will charge at 2Amp or so. In practice, they will probably be a lot lower, but your chances are improved. Not many people will break out an ammeter and check, after all.

Perseus kernal has fast charging settings.
What ttabbal wrote is mostly correct. But the problem lies within some input voltage protection logic tied to the charger chip of the phone which is extremely (and too much so) sensitive.

Can people stop calling it fast-charge, it's an idiotic term which technically means nothing. While most kernels have some sort of charging speed configuration options, they're all useless in regard to this problem as the current in the end is decided by a different logic. You'll have to disable unstable power detection and that's the only way to make it work and fix the problem, unless you go hunting down high quality cables and chargers.
Personally I also encountered the problem as my stock S3 charger, as many others here have reported, has deteriorated and it would only charge at an effective 300mA. I disabled unstable power detection and now it charges at the full given current limits, without any issues.

Hi
See lots of 4000+ batteries and standard 3000, but are there any good 3500 or 3800? (want to keep normal back, no added bulk)
Ones I have seen look cheap and nasty (no brand) and I have a feeling they will add nothing extra.
Anyone got a 3500/3800mAh, did you get noticeable difference, worth it?
Thanks
Its not possible to have a higher capacity (mAh) Li-ion battery without increasing its size.
I personally use the TrendON LG G4 Battery kit and have been really happy with it. While the batteries last about ~75% as long as the OEM battery, it comes with 3 (depending on the bundle you choose) and a wall charger. Really great deal and an 18 month warranty! http://www.amazon.com/TrendON-3000-Spare-Replacement-Battery/dp/B010P2BQ2S
Hope this helps!
I ordered a (supposedly...) 3500 mAh battery online. It's the same size as the stock battery. My expectations are low, most likely won't actually live up to the rating etc. Either way I'll let you know after it's in my hands and I try it out for a day or two. Hoping it doesn't turn my beloved G4 into a pile of melted plastic.

You haven't paid much attention to LIPO packs since the beginning, have you? LIPO batteries are constantly getting smaller while packing more and more current capacity. A denser battery pack is possible just as a LIPO pack with the same size dimensions having less capacity than 3000mAh
Bit shocked Mugen have not done one, I see they tested a 3100mAh, but a extra 100? is it worth it, thought for sure they would have tried a 3200/3500mAh, but all there is out there is cheap no name stuff.

Well, my 3500mAh arrived. It appears to be very well built. In no way does it feel or look cheap. It is ever-so-slightly thicker than the OEM LG battery, and also slightly heavier 49.4 grams, compared to 46.3 grams for the LG.
The extra thickness and weight is to be expected for the slight (claimed) increase in capacity.
I popped it in and it fit perfectly, snug but not too snug. Just enough that I could hold my phone without the cover on, screen up, and the battery would not fall out. My stock black leather back fit right back on without a problem.
Powered on and the charge level was right around 80%. I charged it to full, then ran down to 5% or so. I repeated that a few times before evaluating it's performance.
Sadly I didn't do much to test the stock battery, but I can tell you I was never able to get more than 3 hrs of screen-on time. Same with 4 TrendOn batteries! The TrendOn batteries also occasionally caused problems where my phone would shut off when taking a picture with flash. Wouldn't turn back on until I switched batteries. Maybe it would've had I plugged in a charger, but I never tried. That would happen even if the battery was over 60-70%.
Also using the TrendOn, sometimes I would put a freshly charged one in and my battery level would be stuck at 80%, never going up or down. Usually that would "fix" itself after a few reboots.
After using this battery for a little under 2 wks I can say I'm very pleased. I regularly get over 4 hrs screen-on time now. Using auto-brightness, and doing random things like browsing Reddit, XDA, watching YouTube videos, streaming music with Pandora or Spotify, etc.
I've taken many pictures with and without flash and haven't had a single reboot. Also haven't had the 80% bug. Both of which plagued 3 out of 4 TrendOn batteries.
Charges just as fast as the LG battery. Just over an hour from ~10%-100% using a QuickCharge 2.0 charger, and stock or equivalent cable.
I guess only time will tell if this battery continues to perform as well as its been, or if it decides to incinerate my phone... Since I received it, I haven't taken it out. Haven't needed to as it easily gets me through the workday(sometimes the entire day) , even with moderate to heavy use. Now that I have a QuickCharge 2.0 charger at home, and in my car, I don't even carry a spare battery. 15-30 mins on one of them and I'm good for several more hours.
I'm not sure who makes the battery. I don't think any name is printed, only "Made In China." I bought it using the BangGood app. I'll update if I experience ANY problems.
any link or screenshot please? would like to get one

Maybe it would've had I plugged in a charger, but I never tried. That would happen even if the battery was over 60-70%.
Also using the TrendOn, sometimes I would put a freshly charged one in and my battery level would be stuck at 80%, never going up or down. Usually that would "fix" itself after a few reboots.
After using this battery for a little under 2 wks I can say I'm very pleased. I regularly get over 4 hrs screen-on time now. Using auto-brightness, and doing random things like browsing Reddit, XDA, watching YouTube videos, streaming music with Pandora or Spotify, etc.
I've taken many pictures with and without flash and haven't had a single reboot. Also haven't had the 80% bug. Both of which plagued 3 out of 4 TrendOn batteries.
Charges just as fast as the LG battery. Just over an hour from ~10%-100% using a QuickCharge 2.0 charger, and stock or equivalent cable.
I guess only time will tell if this battery continues to perform as well as its been, or if it decides to incinerate my phone... Since I received it, I haven't taken it out. Haven't needed to as it easily gets me through the workday(sometimes the entire day) , even with moderate to heavy use. Now that I have a QuickCharge 2.0 charger at home, and in my car, I don't even carry a spare battery. 15-30 mins on one of them and I'm good for several more hours.
I'm not sure who makes the battery. I don't think any name is printed, only "Made In China." I bought it using the BangGood app. I'll update if I experience ANY problems.

Well, my 3500mAh arrived. It appears to be very well built. In no way does it feel or look cheap. It is ever-so-slightly thicker than the OEM LG battery, and also slightly heavier 49.4 grams, compared to 46.3 grams for the LG.
The extra thickness and weight is to be expected for the slight (claimed) increase in capacity.
I popped it in and it fit perfectly, snug but not too snug. Just enough that I could hold my phone without the cover on, screen up, and the battery would not fall out. My stock black leather back fit right back on without a problem.
Powered on and the charge level was right around 80%. I charged it to full, then ran down to 5% or so. I repeated that a few times before evaluating it's performance.

Hi All,
Dude your looking on the wrong places. Try AliExpress for Batteries and more! A 3800mah Battery an't going to cut it man. You'll need a case for it. Like mine with a 7700mah Battery. Look here http://forum.xda-developers.com/g4/accessories/2-extended-batteries-test-t3320662 for my testing and pictures
Look here for the Batteries and more http://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20160223124746&SearchText=3800mAh+lg+g4
Edit1: A 3500mah would actually fit without a custom bought case http://www.aliexpress.com/item/2x-3...52&btsid=2dd82693-22fc-46b6-8277-cb8017d83bd8

The 3500mah is the only one that would fit. any higher then a Custom case would be needed. I have one on mine and it's not that thick. I actually bought another case to fit on top of the one that came with my 7700mah battery. just look at my post and see the difference
Sorry for such a late respond but here is the one I purchased http://www.banggood.com/BL-51YF-3500mAh-Li-Polymer-Battery-For-LG-G4-H818-p-987003.html
Saw someone posted the same link a few posts up too. Figured I'd reply to let you all know that it's still working great. Actually had to swap to the original for a little when I was running out and didn't have time to charge. I honestly couldn't wait to get this battery back in. Still getting over 4 hrs screen on time, auto brightness, GPS and WiFi always on, NFC always on, Bluetooth on a good amount of the time and connected. I placed an order for a second one.

It just camein today. Doesn't feel as if it is cheap. Slightly heavier than stock battery. I haav to go through some charging cycles to let the battery settle. Will report back with anything new.
Been using the battery since my last post and well i like it. With stock battety i get no more than 2 hours sot and the new one i can get up to 3.5hrs. An im a heavy user. Using an anker quick charger it takes about the same amount of time to charge both batteries. Although the new battery does look really cheap it doesn't behave like a cheap battery. No over heatings and no shorting out when using too much. I provided some pictures of the battery just in case you want to know what it looks like.
P.S. I do go back and fourth between both batteries when they die out. For the first week of having it i soley charged both batteries inside the phone with the quick charger. Now i have an actual little battery charger which saves me a lot of time between charges.

and I get 2 months on-screen time wit my Optima Yellow Top
the OP asked for a slightly higher capacity battery that fit flush with the OEM battery door, that gave better performance without adding any extra bulk and limiting case options. Of course a 7700mAh is going to last longer than a 3000-3800mAh. But that wasn't his question. They're EXTREMELY limited on case options, and take up a LOT more space in your pocket. It's something I wouldn't go for, but a 3800mAh battery that allows the use of all the OEM backs and cases while giving over 25% more juice sounds quite appealing to me
I've been using both the incipio offgrid, and tumi powerpack battery mods (both are wireless charging variants) and have noticed just awful battery life. from 100% it charges my phone up maybe 15-20 percent, and thats with the screen off, just streaming music. If I'm using the phone (just surfing the web or instagram) the battery dies in around 30-45 minutes, is this normal? I expected alot more out of these. I can just stare at the notification bar and watch as the battery drops, my software is up to date, and I was just wondering if this is normal? Is everyone else getting this awful performance? I expected way more for like 70-80 bucks each...

This is not normal. While I don't have either of these, based on the reading I've done and reports I've seen from people who do, the Incipio off grid should be able to charge your phone up 50-75% when attached. Not sure if you have some crazy wakelock that's keeping your CPU maxed out all the time or what, but dying in 30-40 minutes makes no sense.

When I got it to die In 30-40 min I was on a phone call and surfing instagram. Took the tumi out yesterday with 80% battery in it and had my phones screen off streaming music over Bluetooth. The phone charged up about 25% before the battery pack died. Any ideas on how I could improve the battery life? My moto mods manager is up to date and I don't get any prompts to update anything whenever I snap on the mods
I was surprised when I found this post, so I checked how many percent of battery do I get with a my incipio battery mod. I plugged the mod, my phone's battery was at 15% and the battery mod was at 100%.
Now the Incipio battery mod is empty and my phone's battery is at 50%. So it charged my phone by 35%.
Pretty disappointing for a 2220 mAh battery that costs almost 100€ ...
To me the best use of the mod is to snap it on when the Moto Z Play is fully charged and to chose the option to keep the phone battery at 80%. With normal use, i've seen the mod keep the phone at 80% for up to a day. To me the mod is not meant to charge the phone but more to keep it from discharging.
To me the idea of the battery mod makes no sense.
There is an Aukey 16000 mAh power pack with QuickCharge 3.0 available which boosts the battery in nearly no time. I paid less than 20 Euro.
Who needs such a battery mod with a Moto Z Play which lasts all day under heavy usage?
Who needs such a battery mod when power packs are big, cheap and fast?
Who even needs the power pack if you have a wall outlet with a QuickCharge 3.0 charger boosting the battery percentage in no time? I needed that power pack when the previous phone (Moto X Play) had some hardware defect making it lose power.
Edit: These questions are meant honestly. Are you living in the desert for several days and can't afford to carry a bag?

The battery mods are not particularly useful for the Z Play because if you charge every night, you have basically unlimited battery life. Battery packs are extremely useful for the regular Z, though, which has extremely poor battery life on its own. They're basically mandatory for the Z.
I'm shocked that battery mods can only charge your internal battery and can't be used directly (discharging the mod battery instead of the internal battery), the same way Thinkpads that have more than one battery can do. That makes the $80 (vs maybe $10 for a 2000 mah ravpower) cost all the more eyebrow-raising.
I'd love to use them as a way of preserving the sealed in internal battery's longevity, making the internal battery the backup battery and wearing out the easily replaceable, easily swappable mods instead.

What do you think how a battery should be treated to prolong its lifetime?
This is a serious question. I'm not sure if charging cycles do matter these days. The point which makes batteries getting weak is the age. An additional battery will not help reduce the age.
Of course you should be careful not to be in extreme cold or heat. If the battery is below 30 percent, you should consider to charge it. You should not charge it again if it's over 80 percent. But trying not to use it seems not to really be helpful for the battery to have a longer life, although battery lifetime usually is given in battery cycles. At least this is my experience. If it does not get hot when used or charged, all batteries nowadays start getting weaker a bit after about 2 years, it gets really recognizable after 4 years, and when they are 6-8 years old, they get so low that they may not fulfill there purpose anymore. Cycles? Never recognized any influence for the lifetime. But one hot day with a usage above average where the battery gets hot may really cause a recognizable decrease in capacity.
If you have some source comparing battery lifetime for different use cases (storage, low usage, middle usage, frequent usage, under different conditions of temperature, fast charge and slow charge) I'd be really interested.

Same sources as you, personal experience and basic knowledge (battery life being measured in cycles). I'm not even completely worried about average aging, but out of a batch of millions of batteries, plenty will start to experience rapid discharge early, even without abnormal heat, not to the point of being completely dead, but certainly no longer tolerable. Today's phone batteries might actually tolerate heat better than in the past, having been built for quick charging, which is the hottest a sd625 seems to get.
I've read manuals and battery university and a few tech blog articles all of which have differing advice, just like you and me, but I have yet to find a source I find credible (based on diverse large scale testing not limited anecdotal evidence or in the case of manuals, insanely outdated nicad-era stuff). And, sincerely no offense intended, I'm unlikely to decide cycles don't matter and weight your anecdotal evidence over mine anymore than you'd weight mine over yours. But if you ever find a good source with those comparisons, I'd be pleased to check it out too.

Because I don't want to have to worry about having the charger with me or finding a spot to charge.
I fully admit that I tend to be more paranoid about running out of power than I need to be, but I like to be secure knowing that I should have more than enough battery life, even if I can't charge overnight. I like to know that I can grab my phone at any point of the day and walk out the door with it without having to worry about taking a charger with me.

I quite like just not having to charge for three days. I have the battery mod which I use on the efficiency mode, and I got over a full day out of it. At the end of day three I had nearly 30% battery left. Probably enough for most of one more day.
The other thing for me is using wireless charging. I like just slapping my phone on a stand overnight when I do charge it. It charges slowly, yes, but it doesn't matter if I am charging overnight. I still have access to the quick charger if I need to get a full battery quick!
I use mine on my motorcycle where I'm riding for 10 hours a day. I'm at about 50% in 4 hours and dead by 7 or 8, so I'm hoping with the additional battery MOD that I can get at least 12 hours charge. I'm really bad about remembering to plug my phone in when I stop for a break!
@tag68 : dude I think you totally missed to read what @fortunz was saying, he was only pointing that he would like the Mods to be used as a primary source battery instead of being a "ultra-portable power bank".
Given that there is also a fraction of the power being lost in the form of heat, during charge/transfer, it is even more silly from Motorola not to have the battery used directly. I can say by the 25-35% charge from the Mods estimated from other users, that the efficiency is somewhere around 50%, HORRIBLE to say the least.
And yeah I was reading through both of your posts and good information was provided, although unnecessary friction used (not naming anyone).
I actually have kind of the same idea from @fortunz to prolong the battery life of my Z-play even with the mod just being a power bank.
Saying that the mods (~2220mah) charge your phone anywhere between 25-35%, I can actually take the top 25-35% out of my internal battery use and move it to the Mod.
So I can charge my phone up to 70% before going to bed, and then when my phone reaches 30% during the use next day, I'll just slap the mod.
I can allow myself a lot of variation to this, I will not be religious about it, the topic is to avoid hitting 100% charge, and instead, moving the wear of that 30% usage to the Mod.
According, to many articles, citing just one below, considering the depth of discharges and voltage levels, you guys might do the equation if you like, but according to the charts and theory:
charging my phone twice a day trying not to exceed 70%, will give me WAY more longevity run than charging up to 100% every day.
First charge will be from around 15% which is my normal deadline to around 70% with a wall charger, before going to bed.
Second charge will be from the mod from around 30% to around 60% (hopefully), which will give me portability while charging.
Total screen on time during the day, should be around 10% less, but well worth and I can definitely take the hit if getting more battery longevity as a trade.

In re: friction, I took no offense from the exchange. Hopefully I didn't cause any either.
Good luck with your efforts. I have considered using this app to to stop charging early: https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002 Haven't started using it yet.

Sadly that application requires root... and I don't want to unlock the bootloader and then having to worry about SafetyNet...
For me SafetyNet is green using Magisk 12.0 as root solution, but that may change of course. But it would help for the battery.
Short rant about this topic: It is strange that the owner of a device can be forbidden to restrict the charging. You bought it, you should be able to do these things with it. Introducing SafetyNet is a bad idea by Google. Security should be made by algorithms, not by hardware. Using public key anyone may modify anything, and you can still assure the content to be trustworthy. There no need to prove the Android not to be modified, it is just a bad idea, unnecessary restricting the user. Owner.

There no need to prove the Android not to be modified, it is just a bad idea, unnecessary restricting the user. Owner.

Well said
Thanks for the tip! I'll have it mind!
At the moment I don't feel like unlocking the bootloader because I'm planning to use the moto Mods and these can't be used with custom ROMs yet, and I have no use for root other than changing the work mode on Greenify but it already works well enough in No-Root mode, so for me there is no true benefit.
A good resource for lithium batteries are rc helicopter forums. Helis use speed controllers of many tens of amps, drain the batteries in minutes versus days to low levels and charge them at high speed. What reduces their life is heat, overcharging the voltage or over discharging the voltage. They do not age if left in a partial charge. You can let them sit for years unused and they will lose very little capacity. If you only run them at 70%cycle, they last about 3000 cycles.
Well, that was weird.
Phone at 9%, mophie mod at 100%. Put it on, barely used the phone (even took a nap). About an hour later, the mophie mod is at 50%, but the phone actually went down to 8%. Took off the mod and the phone went immediately to 4%. Ouch.
Mod normally works fine. It'll keep the phone at 80% for most of the day just fine. Not sure what was going on.
