I've been following the great battery impression thread, which discusses ways to tweak the Nexus 4 settings, ROMs, and so forth for maximum run time between charging. This thread focuses on a different battery concern.
The Nexus 4 lithium polymer battery is sealed, and as far as I know, there are still several unknowns about replacing it. We've seen a tear-down showing how to remove the battery. However, as of now, few users have attempted it and there's not a consensus about how easy or difficult it is to do. Questions include:
Even with the correct tools, are the tabs that secure the Nexus 4's back prone to breakage, potentially leaving the case borked?
Is the battery difficult to extricate from its compartment?
Will it a high quality replacement battery become available inexpensively on eBay and elsewhere, or is it this battery, which was not designed to be user-replaceable, too much of an oddball for that to happen meaning that a replacement battery will be expensive and hard to find?
That said, the ease (or lack thereof) of replacing the Nexus 4's battery isn't what I've come here to discuss.
Given the unknowns about battery replacement, my concern is to how to maximize the Nexus 4 battery charge cycles and reduce the capacity drop of the battery over time. It could be bad if after just a year, the Nexus 4's capacity is already noticeably dropping. Not possible? I'm not so sure. Based on what I've read, it may depend upon how we handle charging.
This article at "Battery University" discusses the discharge characteristics of Lithium batteries, and it is my understanding that Lithium Polymer batteries, like the one in the Nexus 4 mirror these characteristics.
My takeaway from the article is:
Charging the Nexus 4 battery before it drops to less than 50% capacity will greatly increase the number of charge cycles before there's a noticeable capacity drop. Letting the battery nearly completely discharge will greatly reduce the number of charge cycles, and therefore greatly reduce the time before battery replacement will be necessary. (Table 2)
Inductive (wireless) charging, while convenient, generates extra heat that will over time reduce the recoverable capacity of the battery. (Table 3)
Having read this article, I am curious about the charging characteristics of the Nexus 4 and which, if any, charging variables we can control as users to maximize battery longevity.
When I first get a new smartphone I try to do a handful of full cycle charges before doing any partial charges. Your battery is still "new" and in the "break in" period. Many users that were the first to get theirs have reported their battery life as getting better. Of course a lot to do with battery are things like your data usage and what you have syncing.

Thanks, but I will again clarify that that I created this thread to discuss maximizing the Nexus 4 battery's long-term life and recoverable capacity, not maximizing run-down time in the short-term. That is already being discussed extensively in the great battery impression thread.
I have had a lot of experience with LiIon batteries over the years and I can tell you that the enemy of them is both inactivity and deep discharge use.
Use your phone as you normally would, but avoid frequent deep discharges. Don't be afraid about the number of charge cycles. Frequent charges are better than deep discharge cycles.
These pups have been designed to be used the way most folks use frequently used rechargeable devices. Pop it on the charger when you can, even if you know it won't be there long enough to be topped off. The more frequent and varied activity the better.
I'll add that I do not currently see an LG BL-T5 Nexus 4 replacement battery sold anywhere.
FYI - The Nexus 4 uses an 800 cycle battery as well so makes it even less of a thing to worry about. My SGS2 still gives me good battery life and it's more than 1yr old already, and i think that is a 300 cycle battery. Remember also that at that 800 cycle mark the battery should still have 80% of it's original capacity. 800 cycles is more than 2yrs of constant use/charge every night and for people that don't so much that could put you in the 3yr-4yr range. If you still have this phone 4yrs from now, i think you wont need to complain if it "only" has 80% of it's original charge.

There is little point in worrying about charging before it's discharged to 50% and/or not charging to maximum. Yes it increases the number of cycles, but is reducing runtime between those cycles, so you have to charge it twice as often using up the extra cycles gained, so overall it tends to even out.
The longevity argument for only partial discharges really only applies at the time of design and specification where the manufacturer can spec a larger battery and sacrifice some of the capacity (by only charging say from 30 to 70%) to get extra charge cycles. Clearly with a mobile phone this isn't desirable to do, as we crave all the the runtime we can get in the smallest form factor possible.

Is the "800 cycle" rating is based on real world usage, or a set of idealized laboratory conditions that few users will actually meet? Many Nexus 4 forum users are reporting running down their batteries to a discharge depth exceeding 90% on a daily basis before recharging. This will dramatically reduce their battery's number of charge cycles. The "800 cycle" rating is only useful if we know the conditions upon which it was tested.

Point taken, although it looks to me like the relationship between discharge depth and maximum number of charge cycles is not linear. From the way I read it, frequent deep discharging can markedly impact battery longevity which is why I'm skeptical of the 800 cycle figure. Given that many Nexus 4 users are currently reporting an inability to make it through a full day without completely draining their battery, those particular users are bound to have shortened battery longevity unless they charge at least twice/day.

Yes it isn't linear, but the advantages are also outweighed by the negatives, such as having to plug it in more often to charge, and if people are struggling to get through the day now on a full charge/discharge cycle.....
The 800 cycle figure is probably about right for chemistry used in the LG Nexus, and most of us will have replaced our phone in a couple of years anyway long before we start to notice the lowered battery life.
The other thing with a lithium batteries is they are like perishable foods, even if we don't use them much, after a few years the capacity has diminished anyway. So even if we only charged the phone twice in two years, the third charge capacity would probably not be that much different to having charged it every day for two years.
So we shouldn't worry about the battery, the best thing we can do is use it as much as possible as it is going to degrade anyway, and we will see little benefit from treating it with kit gloves.
The above also assumes the battery can never be replaced. It certainly is replaceable by the manufacturer or a repair centre, and more than likely most of us could manage a replacement ourselves.

One very important thing to realize is that these 500/800 or whatever hundred cycles it's talking about is not how many times it can be charged, period.
It's not like after the 500th or 800th charge, this battery can never be powered on again.
Read the article closely:
" the number of discharge/charge cycles Li-ion can deliver at various DoD levels before the battery capacity drops to 70 percent."
Also, if you lower the voltage of the charge, it seems battery long term life greatly increases:
"Most Li-ions are charged to 4.20V/cell and every reduction of 0.10V/cell is said to double cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.00V/cell should deliver 1,200–2,000 and 3.90V/cell 2,400–4,000 cycles. Table 4 summarizes these results. The values are estimate and depend on the type of li-ion-ion battery."

When a lithium battery is fully discharged, it isn't actually completely discharged. LG like other manufacturers will have programmed a level that shows 0% on the phone before it shuts down, but in reality this might still leave 10% or 20% or 2% capacity in reserve, we don't know the figure, but presumably LG have set both full and empty charge points to ensure we see around 800 cycles.

Yes you get more cycles, but because you have a battery with reduced capacity, you are having to charge it more. Overall the benefit isn't as great as the numbers make it. If LG wanted to give us 1600 cycles they could lower the charge voltages, but then the battery capacity would have to be advertised at around 1050mAh, meaning it lasts half the time it does now, and will need charging around twice as often.
For a mobile phone with a typical 2 year life span, the priority is to maximum the time between charges while ensuring the battery lasts the typical 2 years of most peoples phone contracts. It isn't a co-incidence that 800 charges works out as a bit over 2 years if you charge every day.
We don't need to worry about the battery, just enjoy using the phone. Also the battery doesn't just stop working at 800 cycles either, it just doesn't hold as much charge, but capacity is lost anyway over time regardless if you use it or not as lithium batteries start to age the moment they are made.

A lot of assumptions there, Phil.
My "priorities" and LG's differ. 2 years from now, some will replace their Nexus 4 with whatever shiny new phone comes along that offers holographic video projection chat and does double duty as a sex robot. However, I will happily trudge on with my Nexus 4 for between 3 to 5 years which is how long I typically own a phone before replacement. I don't need bleeding edge, especially if the bleeding edge is a menstruating sex robot phone. Just sayin'.
We don't know if the Nexus 4 battery replacement will turn out to be either very costly and/or difficult. For those of us who don't plan to toss our Nexus 4 into a landfill two years from now, it pays to know what measures we can take to prolong battery longevity.

Hmmmm....how did that happen...
I don't know if we will really know how good the battery longevity is in this thing until the device is a year old or more. Lithium polymer technology varies a lot. There have been a lot of advances with this tech in the last few years and some companies claim to have developed manufacturing techniques that allow THOUSANDS of charge before noticeable drops in batty capacity. Other technologies developed include the tech Apple uses and advertised in its MacBook line a few years ago that claimed longer battery life and very fast charging compared to Lithium Ion batteries. It all varies. LG claims to have some special tech baked into this battery that allows it to charge to a higher voltage compared to batteries of similar size, but I don't know how long its life is rated at.

Hi all,
I'm very interested in switching to the z3 compact yet my main concern is the built-in battery. I'm concern that the battery might fail after the 1 yr warranty has elapsed. If this happens; I'd be at the mercy of the sony service center. Replacing a built-in battery will definitely cost a lot more than just swapping out interchangeable batteries like I do now with my s4 mini.
The xperia Z line has been around for 2 years now if I'm not mistaken, can anyone share the battery health of their Z device after 1 or 2 years of constant use (those who recharge every night). after the 2nd year did you feel that the battery lasts far less than what is acceptable? and how much did it cost you to get it replaced? or you just sold it and bought a newer generation phone.

It all depends on the way you charge your batteries.
- If you repeatedly using your phone till it's dead or almost dead, then recharge to full, the longevity will be short.
- Longevity is also affected by the length of time it is connected to the charger, the shorter the better.
- If you keep it at 100% all the time, this will reduce longevity ( fully charged = highly stressed battery).
I learned the above from the site below, so more info there:

This is what is happening to my s4 mini now. The battery barely lasts a day on my normal usage. Now I'm hardly using it because I'm afraid it will run out of juice before I reach home. I gets to a low 20% and then I charge it overnight. the z3 compact's 2 day battery will solve this for me, hopefully.

I normally keep my phone plugged in over night so that I can be certain that it will be full in the morning when I leave. This is because my current phone's battery drops by 10-17% overnight while I sleep. I compared that to an 5S running on 2G = 1-3% = awesome. (btw; signal is very ok at my house so I don't think it is waking up due to that)
Thank you for your inputs. I guess I'll have to change how I charge my phones from now on.
Have had my xperia z almost since launch and can't really say t hey I noticed any big difference in battery life. Sure some it prob are would be strange but lot so I notice it.
And for the long charge it isn't that big of a problem, have had my Z in the dock over night every day.
As with all these batteries (Li-ion): if you store them leave them at 40-60% then store them away , they dont like to run fully emtpy (although there probably is some hibernation implemented in the system like on laptops) nor fully charged.I think thats the reason why you also never get a fully charged/discharged device .
Batteries have been getting smarter so modern batteries of this type will never charge to 100% even though they display it (thats why leaving them connected it basically does no harm). I am assuming the Z3C also does it this way.
I recommend "calibrating" the battery once or twice every two months that means full charge , then full discharge, then full charge again but beware that if your battery is near death this procedure could be its killing blow due to bad cells .So just do it if you do not experience any problems with the battery, like a sudden drop in battery. Otherwise you can calmly "let it learn" its real capacity.
But again technology has also not slowed down on batteries and as this is a modern device which I think you cant kill with normal usage just extend its life (a bit).

I also had my XZ since launch, with BT always on I use about 50% during a normal working day.
Have my Z3C for about 3 weeks now, so only time will tell whether the battery lasts. However, this is not my first Sony phone and the Xperia U (about 2 years old, now being used by our son) hardly shows any degradation. Same goes with the Xperia M (1 year old) and still going like new. Adding to that, I never actually paid much attention to when or how I recharged....
Batteries don't usually go bad all at once. Instead, wearing out is more of a gradual process of not charging quite as high and discharging faster. Since this battery is so good to begin with, I would think compared to other devices you could buy right now it will last a long time.
A year from now you'll still get more life out of even an abused z3c battery than you'd get out of that undersized cell in a brand new Moto X.
Hi there
I am considering of buying a new phone.
Is the HTC One M7 a good choice?
Because the phone is almost 2 years old and is probably not beeing produced anymore.
So I am affraid that the battery in the new phone already lost capacity.
Anyone who has some advice around this topic?

Lithium batteries doesn't loose their capacity when not used (yes but its an inconsiderable %) if they are stored adequately (not in extreme heat conditions). Lithium batteries have a discharge rate of about 1-1.5%/month when not in use so in the worst case, your battery will need a longer initial charge. Keep in mind that mobile phone batteries are expected to last about 3 years when used daily. Lithium batteries doesn't need maintenance or conditioning and there is no "memory effect" unlike NiCad batteries.
What will make a lithium battery to loose capacity is
the amount of discharge/charge cycles --> inevitable
Temperature of operation: when temps increase, life span decrease. So avoid overheat conditions like playing intense game and charging the phone at the same time.
the amount of deep discharge: a lithium battery will last longer if you avoid deep discharge, so its better to charge your phone daily instead of waiting it to reach 0%.
you can expect that your battery will loose about 10% of its capacity after 500 cycle (general rules for lithium batteries), sometime it can be more sometime it can be less.
Charge rate: when charge rate increase, battery life decrease. So yes charging your phone using a fast charger will decrease battery life.
Yes. Still worth buying. My experience though is that my battery after a year and a half of use has degraded somewhat (duh). Lately it has been more noticeable with large drops, but I've been very tough on this thing. I am going to be taking the phone apart later this week and replacing the battery. It looked intimidating at first because there are so many steps involved, but really once you get the One open, it's pretty smooth sailing. There are plenty of good methods out there for getting it open without damaging it.
The best thing about the m7 is there is plenty of development still going on, including official and no official and stock. Love my One.
A friend of mine went to a Samsung Service Center with his s9Plus for couple of questions. One of those questions was what the best method is for charging phone. They said minimum 5% then charge all the way up to 100 in one go. I was surprised with this answer since I did a lot of online research on this matter for my Note 9. I concluded and that the pro's are talking about keeping it between 20% and 80%.. and I'm doing that ever since..
Do we have an expert here on this matter?
Not an expert, but plenty of apple and android devices that I have kept for several years and never wore out a battery. My iPad mini is around 5 years old now, no issues. Galaxy s7 edge traded at 2 years old with no battery capacity issues. Old Samsung Galaxy Note 8 (the tablet from like 2012) still going strong, etc. I charge my phone when I feel like it (usually overnight) and take it off charger when I need to. I don't care if it's charged fully, I don't care how long is been charging. My life does not revolve around my phone battery percentage. This 20% - 80% thing is stupid. Your battery will far outlive the useful life of your phone.
Not an expert either but I do have the capacity to research this stuff myself. The age of the battery actually has little impact on it's capacity, so just because a device is X years old, doesn't mean it's battery capacity is going to have dropped significantly. It's the charge cycling of the cell that causes the degradation, temperature, depth of discharge, charging speed and the number of cycles a battery has had are more important. While I'd take the Service Centre rep's advise with a grain of salt, Samsung have clearly put a great deal of work into refining their battery technology, so do you need to worry? Probably not.
Although, if you think the battery will far outlive the useful life of your phone, look at Apple and all the batteries they're having to replace.
That all I know, and trust me, my devices go through plenty of charge/discharge cycles in the 2 to 8 years that I own them.
Hello fellow members, I hope that everyone is doing well and that we're all safe. I'd like to write about a problem I had between flashing stock & custom roms (thank you to all the developers for their hard work & patience). Flashing custom & stock roms I noticed that the battery would not display correctly it's percentage (about 15% less) on standby or when charging. This would affect signal coverage, and I would have to frequently close my phone and put my battery back in for a quick fix. Another important problem was that the phone would start shutting down before discharging correctly, till the point that my phone powered down my at around 57%. After trying all the solutions suggested here by other members (wake lock, wiping battery stats,etc), I was starting to consider that maybe it was time to upgrade. Try as i might, & taking into consideration what I actually do with my phone (ebook reader, music and video player, tv remote, game emulator console, the list goes on), there isn't any phone on the market that I consider could adequately replace my Note 4. So as a last resort I discharged my battery completely while in Twrp recovery and swapped it out with another Note 4 I have to charge. To my surprise the battery started discharging in a nearly perfect manner and seems to be holding up pretty well now after a few charges (considering it's a second hand phone and that the battery is not original). So I hope that this can help anyone out there having battery issues and is willing to give this a try. Cheers
The power management is sort of witchy even on the newer Samsung's.
Fine when it's working right and downright inscrutable when it's not.
Hi Blackhawk, thank you for the read & like. I really have to thank the Xda forum & fellow members if I tried this solution in the first place. I absolutely loathed the idea of having to change my Note 4 due to random battery shutdowns. New phones out on the market have (in my opinion) really bad flaws such as screen bleed, faulty screens & digitizers, ecc, & my Note 4 has been durable with a 6 euro case & 5 euro screen protector. The hardware might be a bit limiting for today's standards ( technology devolops in leaps & bounds & sells even faster), but the everyday user wouldn't even notice or care if it wasn't for clever marketing & the notion that after a few years we have to buy something "new". Anyway, all the solutions I read on the forum really helped me out to reflect on how to solve my problem in the first place, so I hope what I found out can help someone else out. Good day to everyone
My 10+ was ok until I did a full charge on a slower charger overnight. I normally never do that and usually do only midrange partial charges.
It auto shutdown then when it got down to 15% when I was trying for a battery recalibration.
Normally I never go below 30%
Then fast charging started screwing up too.
Tried almost -everything- to no avail.
Perhaps a charger or cable failure was coincidental; don't know still waiting for the new brick/cable.
If it still continues after the new charger I'm looking at either a battery failure, port failure or a hardware power management failure most likely.
I hope it's the charger/cable*, lol
No doubt the battery issues are quit the pain.
*the milliamp draw drops a lot when it falls out of fast charging mode so the battery probably isn't the culprit. The temperature sensors seem to be fully functional. Will try yet another recal after the new charger arrives. Grrrr... what a time whore it is.
Update: it was a battery failure at less then 1.5 years. Because it's always in a case I didn't notice the rear cover was bulging, a lot.
I was very fortunate it didn't damage the display.
All those symptoms I described are a battery failure in progress.
A Li is considered degraded when it reaches 80% of its original capacity, the end of its useful service life. Degraded Li's are more likely to fail.
Any swelling is a failure
Today that same N10+ is in my hand still running like new although it's once again nearing battery replacement time.
Expect a 1-2 year battery lifespan on a heavily used device. Battery replacement is just part of normal maintenance.
