I red last week somewhere that a liion battery lifetime isabout 300 times charging, does anybody now or this is true?

You can find there answer to your question..
The life span is dependent upon aging (shelf life). From time of manufacturing, regardless of whether it was charged or the number of charge/discharge cycles, the battery will decline slowly and predictably in capacity. This means an older battery will not last as long as a new battery due solely to its age, unlike other batteries. This drawback is not widely published.

same, my diamond is connected about the same amount of times per day, and then left on charge when im at home to ensure i have adequate battery, eek!
I think the 300 times charging is refer to 300 full complete cycle of charging. It need to be refer to complete a cycle from fully discharge to fully charge. If you charge your battery from 50% to 100%. It is only 1/2 cylce.
Anyone can correct if i'm wrong.
I think a complete discharge counts as 1. If you charge the battery now and then without letting it discharge completely it will last longer. This is quite Li-Ion specific.
In heavy usage a battery lasts for 2 years easy.

Even when you charge it 2 times a day? This should mean about 1400 charging?

Right, firstly, forget anything that has been written above. 300 is crap. (the film '300' isnt tho)
lithium ion batteries generally last longer when kept topped up, rather than cycled.
The batteries in out Diamonds are lith ion, but have been specifically designed for top up charging, therefore last longer.
you can expect your battery to last for 3 years of continuos use, unless there is a fault or it is damaged. It will slowely deteriorate over time.
I have just bought a new battery for my laptop, which is Lithium Ion, as was the original. This is after 10 years!

OK. I know it is out of the topic, but i still want to say: My laptop which is a precision workstation laptop's battery only last 1 year.
So, it is fair that if you discharge and charge frequently, it will deteriorate faster. This is fair enough.
Li-ion battery life - the facts
Skipping back to the facts for a moment.... the HTC Diamond standard battery is a Li ion battery with Co chemistry.
1. Li-ion batteries last between 300-500 deep cycles (from 0% to 100%).
2. Partial recharges are good. A partial recharge from ~25% to ~75% is less damaging than a recharge from 0-100%, and only counts (roughly) as around 1/4 of the impact of a deep cycle. Li ion technology has no charge memory effect, which means that the battery capacity is completely unaffected by partial charging (n.b. this is NOT the case for NiCad or NiMH technology).
3. Li-ion batteries also decay at a constant rate over time, dependent on temperature, and regardless of use. They lose around 20% capacity per year at 25C, but this is increased at higher temperatures. Shelf life is optimised by keeping unused batteries at 6C (fridge temp) and with ~40% charge. But do not freeze them!
4. 100% charge causes accelerated decay rates. So keep your battery below full charge.
5. Deep cycle the battery occasionally (~once per 30 charges), to recalibrate your charge meter. Otherwise the charge level shown will become inaccurate.
6. Key advantage for Co chemistry is high energy density - up to 200mWh/g. Key disadvantage is the charge/discharge limit, which is ~1.2 coulomb.
7. Conclusion is that you can expect your Diamond battery to last for ~3 yrs of hard daily use. If you take care of it, it will last for double that time.

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!
Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/
right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full
Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.
I plug mine into a wall charger or my laptop...
At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.
i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.
Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.
On the charger before reaching 10%, around 20% or higher if it's possible.

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.

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.

Huh, it even makes sense when explaining to other people...
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.

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.
If i use the official fast charger .....charge up to 100% the next day I barely get 16 hrs and 3 hrs screen time..wireless charge slowly and I get 30 percent more .
Anyone else see a difference??
Uk unlocked s21u for reference.
You sure there are no other factors involved?: types of apps you ran, heat, etc.

That sounds interesting! Would love to look into this a little deeper.
Could you describe this in a little more detail please? Like when do you start charging, how long it takes with each method, what your usage pattern is like, and what you mean by 30% more (SOT, Standgy, or literal battery percentage remaining)? And any relevant screeenshots would be much appreciated.
Fast charging will not engage if the temperature is too low. It will remain disengaged for that charge cycle.
Charging is an electrochemical reaction that needs a certain temperature range to function properly.
Minimum start temp is 72°F but 82-90F is optimal.
Anything below 72F brings the risk of Li plating which will permanently degrade the cell.
Charging will also shutdown if the battery temperature goes too high.

I don't think OP is talking about speed of charging. We're trying to discuss battery life with different speeds of charging.

It should be near identical.
Android battery capacity sensing always left something to be desired.
Battery temperatures should be made the same when comparing.
Try comparing battery voltages rather than indicated %

Depending on how fast the battery is charging it may shutdown at a lower charge level to avoid overshooting the correct shutdown voltage.
Samsung is said to be very conservative with their charge curves... I wonder why
Samsung should be using graphene batteries by now. Instead of throwing all their resources at the Folds, which never have sold well, they neglect their bread winners. I just reamed them out over that today

Said they should be using them already, among other things. Before the 10+ was released there was speculation that it might have a Graphene cell, lol.
I was barely aware of this technology until a few days ago... it be cool and it's in use.

30% more seems to be a huge claim .
5%-10% could have been a margin or error.
I'll have to do some tracking and get some screen shots . I normally wireless charge overnight and it says 100 % every morning and I use 70 % battery on average . But 1 day a week I have to charge using the lead . I only have the "super fast" charger and lead and the next day the battery is always worse by quite a way . Dead by 19:00 hrs. Similar usage most days . Its as if on fast charge it says 100 % but is way down.
As said I'll do some more investigation.

You know that you can toggle OFF fast-charging and super-fast-charging in the battery settings right?
Try that.

Samsung better listen then.
These batteries should last us 4 years easily. Anything less than that is a rip off.

With heavy usage the Li's are good for 1-2 years. Maybe better in a temp controlled environment.
I stream a lot and that's hard on the battery which is why I now say... live and let die
It's typical for batteries to last longer the slower they're charged. If you're using fast charging when plugged in, you'll see a decrease in the amount of charge that is held throughout the day, compared to wireless charging which is quite a bit slower.

Are you sure there aren't any other elements at play? Examples include the applications you used, the temperature, and so on.

So you're saying if one battery is slow, one is fast charged, both to 3.2 volts, the slow charged one will yield mAhs.
Unless the battery is degraded I have my doubts that it be a significant difference.
