A "Battery Care" trick to always limit charge at 90% and extend battery life
It is well known that keeping modern lithium batteries always 100% charged reduces battery life
Several laptop makers have introduced software solution in order to keep top charge around 80% limit. I was glad to know that Sony offers a "Battery Care" feature, a way to limit battery charge in our Xperia 1 II.
But the choosen approach is too soft in my opinion: Battery Care tries to learn when I put the phone on charge and when I unplug it and makes sure it is quickly charged to 90% and then injects the final 10% just before I unplug it my phone will ideally stay 100% charged just a few minutes. It just works if my behaviour is predictable and still tries to charge the phone at 100%.
This how the automatic Battery Care setting works. However I just realized that using the custom setting in a tricky way, I can make sure that my phone will never be charged at more than 90%
I just have to find a time when I am pretty sure my phone will never be connected to the charger. For me 5 in the morning is a good choice, I never leave my phone charging at night.
Then I set Start charging time at 5:01 am and Target time for full charge at 5:00 am. (To reach Battery Care settings: Phone settings > Battery > Battery care)

When plug the charger and Battery Care is activated, I get a notification.
When I unplug the charger I receive a message warning that the charge is not yet completed. Since this is exactly the wanted behaviour, I dismiss the warning and check the flag to disable such warning in the future.
The result is that my phone will never be charged more than 90%.
To stay in a more ideal charging range 40%-80% I also use an app with an alarm that alerts me when the charge is outside this range but with this custom Battery Care setting I have a safety net and I am sure that even if I ignore the alarm, the charge will never be excessive.
By the way another tip to prolong battery life is avoid using quick charging when possible, so I use my original charger (or my PD compatible charger) just when I am in a hurry, otherwise I use an ordinary charger.
Thank you very much for your tip!
Your way works for me too. [emoji16]
And I thought all the time that this battery care thing is useless because it doesn't fit my needs (stop at 90 %) and turned it constantly off - for years.

Too bad that this function is not versatile enough and we have to use these tricks to do something with it.
I don't know much about other Sony phones, how long has this feature been around?
My XZ Premium had battery care, but it was automatic. If my sleeping patterns changed, like on weekends, or on vacation, it would fail to activate because the phone predicts my sleep patterns in order to activate battery care.
Enter the Xperia 1 mark II. I was ecstatic when I found out it has a custom option, where I set the target time. This way battery care is NOT hit or miss. I love it.
Settings > Battery > Battery Care > custom
Do you know that when battery care is turned on, the maximum charge is 90% even if it displays 100%

The screenshot says the battery gets loaded to 100%, after pausing at 90% at night time.

But having in between 40-80% means you have to charge it more frequently, so, doing that doesn't also kill the battery life?

What charger are you talking about? I actually tried this yesterday, the original charger that came with mi X1 II was a 18w charger.. and it does charge the phone way too fast for my liking(around 1 hour). So, i tried the original charger that came with my older XZ1, and oh boy, almost 8 hours later, the phone didn't even make it to 50% charge (from 15% when I plug it)

Yes you will need to charge it more frequently but you can perform much more charging cycles before affecting battery life: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

I agree the fast charger is too fast and and charging fast will shorten battery life too: https://batteryuniversity.com/learn/article/ultra_fast_chargers
I don't know about your XZ1 charger but I guess any 1A USB-C charger will do the job. At work I'm using a common USB Monitor port with this adapter (https://www.amazon.com/PortaPow-3rd-Data-Blocker-Pack/dp/B00T0DW3F8/).
Why not built in on phones ? I see chargie limits and cuts off your charger at xx %0. By Bluetooth signal. Great idea so ez to have bt chargers do the same

i just got my 3500 battery for my evo i charged it over night but when im using it today it seem like im using my stock bettery 4 hrs already down to 68 percent. i didnt talk much and i didnt surf much watch little bit of youtube.
so many variables, kernels and all that. try calibrating, full charge and resetting batt stats if you didn't already.

I am having the same issue, and from what I have been told, you MIGHT need an external battery charger to get the battery to FULLY charge. Something with the Evo stops the extended batteries from fully charging to their capacity.
There are many of us who believe that the algorithm used to determine battery charge capacity is flawed. When the 3500 mah battery is truly filled to capacity, battery life is amazing. I go through a routine to get my Seido 3500 to completely charge. Place the battery monitor widget on your main homescreen (it is free to download from the market) I charge it until the LED turns green or until the battery monitor widget alerts me audibly. Yes, it can be set to emit an audible alert when the battery reaches 100%. Afterwards, I unplug and wait 60 seconds. If after 60 seconds the battery monitor widget displays less than 100%, I resume charging. I repeat that process until after 60 seconds the widget still displays 100%. Once that happens, I can easily get over 24 hours of use from my battery. My routine is somewhat tedious, but it is effective. Like others have stated, a dedicated charger for the Seido may work better. Anyway, I use this same routine with the stock battery. I hope I was helpful to you.

I think I will give your method a try and see if that will work for me. I get approx. 5-6hrs on what shows a full charge on my 3500ma battery at this point.
I charge my battery til light is green, then leave it on for ~2 hrs. Look at the waveform on bmw. You'll notice after the charge level reaches 100%, the mA waveform looks like a saw tooth waveform. Initially it will be a high frequency pattern, then it will begin to slow down... Once it reaches this slow down state, that's when I consider my phone charged.
Here's a visual of what I was referring to above. The phone's on the charger the whole time, unused (idling), screen off.
mA on top, % on bottom.

Same graph, mA on top, mV on bottom
to add another method to the mix it's similar, not trying to knock on any of the others mentioned at all
I found that the most accurate way to utilize the BMW for a full charge is reading the mA's..
..after either placing widget on home screen or activating >menu>settings>monitoring preferences>monitor without widget>history update rate>60sec..
..then after light turns green check mA's in history it will be positive mA until it goes from triple digits to double then single when it reaches zero its at capacity/full then it will stop charging and start to go into negative mA. unless its a sbc kernel it should keep bumping a single digit mA if nothing is keeping it awake..
..unplug at zero and it will stay at 100% for a long time on a extended battery. best I got was 10 hours (at100%) with minimal use and 5 with moderate on a 2400mAH.

I, too, watch the mA using the battery monitor widget (bmw) and many of us used to charge the battery and wait until the mA dropped to 0. The problem is that many of us could never get to 0 or by the time it got to 0 the phone had been charging for about 8 hours...of course I'm being overly dramatic here...lol...The point is this: when the phone's LED initially illuminates indicating a full charge, chances are it is not full and you will have to employ some additional charging methods to truly get a completely charged battery. Several methods have been offered here. Pick one or try them all and then decide which one is acceptable to your tastes and patience level. Take care.

@madflasher, your battery history log is indicative of a SBC kernel. Is that what you are using?
A non sbc kernel has a bump type strategy, while sbc is trickle.

Hey guys,
I've tried Googling this problem but haven't found any real info or a solution. I have a Verizon Galaxy Nexus with the official 210o mAh battery. For the life of me, I can't get it to charge anywhere close to 100%, not even 95%. It seems to stop right at 89%. I'll leave it on the charger at night and when I wake up, it's always showing 89%. If I go into the battery info , it will say 89% not charging. Is there any way I can get it to charge into the 90's? I'm sure it's not a software issue since I've seen this on AOKP b40 and M6 as well as Jelly Belly 3.4 and 3.9.
Wipe battery stats, re calibrate the battery, it could be a kernel problem, completly drain battery and recharge to full with phone turned off. These would be my course of actions. If all else fails maybe replace the battery.

Thanks. I've tried different kernels (faux, franco, trinity, lean) and I still see the problem. I haven't tried wiping battery stats/recalibrating since I've read it doesn't really do anything, but I guess it's worth a shot.

OK, so I'm seeing the same issue with the standard 1850 mAh battery. Stuck at 89% on the charger and the battery stats says "not charging" while it's on the charger. I've tried the standard Gnex OEM charger, my wife's SGS3 charger and my old Droid X charger and all say the same thing. So strange...

No, of course not. Plus, if it was an issue with the micro USB connection, wouldn't it simply not charge altogether?

I had an old Droid X that wouldnt charge past a certain point but I could fully charge my battery in my girlfriends X with the same charger so i dunno
Tested on different phones
Here's my issue I got since I rooted and flashed JRO03C Jelly Bean Rom.
Since then I've tried many roms, battery calibration (that I learned, does nothing), tried many "fixes" like disabling everything while charging, realingning the usb pins...
The fact is that : My battery is actually charged 100%, but shows from 74% to 86% (depending on the rom).
If I take my battery and put it in another Galaxy Nexus that hasn't been rooted, it gets 100%.
If I take a 100% battery from that unrooted Galaxy Nexus and put it in mine, it shows only 74% to 86%.
Sometimes, the battery gains % while I use it (It's a 74% when It's not charging anymore, half an hour later it shows 76%)
I don't seem to have lost any life time, but here's the problem as I see it.
Either my phone cannot properly analyse de output of the battery, or there is sont slack connectors inside the phone that actually dont get 100% output from the battery.
Take it to Verizon, show them, and they will give you a replacement.
I'm having the same issue as the OP, my battery was fine until about a few weeks ago. Nothing changed as far as ROM or kernel go. I have the Seidio 3800 though. My phone just refuses to charge completely even when turned off and charging. The animation for charging that last little bit literally stays on forever. I left it on the charger for almost 8 hours after this really started to bug me, and upon turning it on I was greeted with 88% and it quickly dropped to the mid 70%'s where it floats out for a long while. This is my second battery from Seidio, the first didn't work with NFC and charged too 100% just fine. The OEM battery will no longer charge completely either.

Yeah, as relevant as your post is, no. My batteries have all been NFC capable, one was defective and didn't work. I don't even know why you posted all of that, the last two links weren't even relevant to your point. I think the whole NFC token thing is fooey anyway.
The issue at hand here is my battery life being miserable and reported very incorrectly for virtually no reason at all.
Relevant because it also has to do with chargers used if they don't have same voltage as original or it messes up the nfc. Just saying the batteries, phones, and chargers have to be the ones they can with. Also same info on Samsung site, fine print at bottom. Anyway, just trying to help because I had same problem and don't anymore.

I'm using the OEM charger and cable, always have.
Your first link goes to a Verizon image talking about a possible less than stellar experience with NFC on the Gnex with using other batteries. The second link talks about compatibility of batteries between the GSM and CDMA version of the Gnex. The last link isn't even about the Galaxy Nexus, it's the GSII. None of them mention chargers/voltages/messing up NFC.
Edit: Back to the task at hand, I was just wondering if the OP ever got his battery life figured out, or if he just replaced the thing.
I've been noticing my battery drain about 3% on idle after taking it off charge. It's really annoying as 3% to me is too much. I've attached the battery screens to this post below.

Device Idle is responsible for 1.32% drainage from your battery. No problem here. If I'm misunderstanding, please rephrase.

Actually This is what I was referring to, when using the phone the battery drains nice and slow. better than I would expect to drain during screen on time. But when I take it off charger at 6 am and leave it in place and come back at 11 or 12 am I lose about 10% which shouldn't be normal imo. See below:

looks to me that ur messaging app is going crazy...everything else looks normal.
what can I do to fix this? Its annoying. And no this shouldn't be normal, I like everything about the stock rom and wouldn't like to root just for the hell of it. But this actually has me thinking, (still leaning towards no as I still get thru the day) but would like to get if fixed non the less.
I noticed the same thing. When i unplug it in the morning it drains faster. But when im waiting for the fully charged notification to pop up then unplug it lasts longer. Its strange, maybe has something to do with charger. Do they have "safe mode" after fully charged to prevent overcharging or something?

I always wait for the battery fully charged unplug charger notification to pop up before unplugging. So that doesn't seem to be the problem.
Faster drain is normal from 100% to 90%. It was explained to me that when you leave the phone on the charger overnight it charges to 100% and then allows it to drain some, then starts recharging again. You may really be at 95% when you pull it off the charger despite what the phone is showing.
First, get Better Battery Stats. It can help you figure out whether something is eating your battery abnormally.

Also, I highly recommend GSam Battery Monitor It might be a little easier to understand than BBS, but I like and use both.
Finally, read this: Your battery gauge is lying to you!

BBS should be the best app to find out which process is your problem.
This phone gets hot randomly, guess it was just humid in your car. I feel like all this battery talk is useless android has never been good with battery life. This phone is huge and powerful so battery drain is going to happen. Also depends how long you had battery, how much you over charge battery. I read in several places that after 3 to 5 months of use batteries tend to drain faster.
Your best bet if it's such a big issue is getting another battery with a separate charger. Honestly in this day and age these smartphones should come with an extra battery lol

My battery and phone are both less than a month old, as for humidity that doesn't drain a battery from 50-0% on idle in a few hours. Also I've posted new screenies, messaging used ~20% without being used and stats showing 0s awake. maps did something similar despite disabling all location services and unticking all boxes in the gps submenu. My issue isn't bad battery life, its idle battery life. I shouldn't lose 2% per hour or more when I unplug and go back to sleep.
My battery jumps from 42% to 100% while charging.
When i had first noticed this problem my battery used to jump from 75% to 100%.
but after trying numerous ways to calibrate the battery , everything resulted badly and now it jumps from 42% to 100%.
Please share your experience regarding such an issue and if u have figured out a way to fix this.

so many people facing that problem, we still don't know what cause it, is it software problem or hardware problem, but in my country (Indonesia) someone from Indonesian asus forum facing that problem and he brought his phone to ASUS service centre, he waited for about 1 week, and after he got his phone back asus had changed the motherboard and the battery, so I think battery jump is caused by hardware problem.... cmiiw
How long does it take for battery to jump from 42% to 100%? The 2.3GHz plus 4G ram (ZE551ML)" is bundled with 18W adapter which has quick charge. Please see the following link regarding quick charge: http://www.asus.com/us/support/FAQ/1011185

I had the same problem with an lg G2. If it jumps that much in a couple of seconds then it is really hardware, can be the charger but most of the time its the battery and internal power supply. You just had a bad luck, it can happen anytime to anyphone, Asus have excellent support. Contact them by phone.
p.s: Nice to see Asus staffs posting on xda.
from 0 to 42% it takes around 1 hour after that It jumps instantaneously. to 100%
Yeah i use 18W adapter.
I get battery backup of around 3-4 hours only.
My problem is different my problem is fast charging no working takes ages to charge says 2 odd hour charge or 1 hour 52 and it still takes ages plugged it in 2day 2 charge it said 7 hour I thought wtf anyone know how to help please

Same problem for me, so i have installed an app for monitoring the charge level, it jump from 66% to 100%, it's an hw or sw problem?

I cannot be 100% sure as it never happened to me with this phone but with my old g2 cellphone , it was hardware and I had to replace it. Your best bet is to call Asus by phone.
@kumarsaurav11, 0 to 42% should take much less than 1h. It should be 0 to 60% in ~38 min with that 18w charger. Same advice here.
Mine goes from 40 to 0, 3rd time in a row, brand new, just received it this morning, ZE550ML, if problem persists by the end of the week, I'll be returning it first thing this monday and getting a Mi 4i instead.
Mine is jumping from 78 to 100..
It charges to 60 like at quick charge and then after that it gets super slow..like takes hour+ to get to 78 or so..is purely software related cux in getting around 5-6 hours of sot similar to any user with no jump problem..hope it fixes tho
Plus its happening to half of the users that cant be all hw related..
We are mostly running 2.19.40.22. Never had it with my zenfone 2 4gb ZE551ML, I don't know about the 550.
Yes, quick charge is programmed to only charge up to 60% 18w 9v 2a, then it will charge at a lower than other phones speed at 7w 5v 1.35a, specs are printed on battery heatsink. Charging is 2x slower after 60%. It could be for safety as quick charge will heat the phone fast.

I know but it cant be a hardware problem if all of sudden after v2.19 ALOT people start complaining about battery jump issue..im on 551 tho..
To really know if its hardware, reboot in recovery, clear data&cache, then flash the original firmware from asus website. Start with earliest firmware and try to pinpoint with which one does this issue occure or not.
Does anyone know if cyanogen mod fixed this issue?

This is most likely hardware as I stated earlier. Did it happend to you in Stock?
Just arrived my zenfone 2 from assistence, with a document says:
Fault found: Battery error
Article: SW Update
Testing now and i found that the battery now jump from 78 to 100 instead of 66 to 100.

I had this problem too, battery jumps from 70% to 100%, so i did a calibration and now the battery is perfect (I got double autonomy also).
For calibration:
1) Discharge the battery under 10%
2) Switch off the mobile and charge it 2 hours more from a full charge
3) Unplug the cable for 10 seconds, then plugin again and charge the mobile for a few minutes
4) Switch on the mobile with the cable plugin and when the android system is fully loaded, unplug the cable
All of this for 3 times

Just for compare, if you or anyone can install "battery monitor widget" app and tell me the voltage of the battery when it is full charged, mine is 4367mv.

So I charge my phone today from 32% to 100% in 1 hour and it seems like from the videos other guys get a 0-100 charge for that time. So I was thinking that either I have slower because I am using a UK-to-EU adapter for my charger (got it from UK) or that this speed is the typical one. What's your speed guys?
I like to charge my phone slowly (less than 10W - 3-5H charge) overnight which helps improve battery life.

1C charge means 1 hour charge from ~0 to 100%.
2C charge means 30 min charge.. Why would you want to do that to your battery (half capacity at 500 recharges)?
Overnight at C/3 to C/5 does great things for the longevity.
The state of the phone also matters. Wifi, bluetooth, mobile data, music, video, apps, brightness, photo, camera, sensor, power save, battery temperature, surrounding climate, ... etc.
Adapters may also have their maximum output capped. Check on it's spec.

The adapter doesn't have any specs unfortunately. I just bought a EU charger from Aliexpress. Hopefully it charges faster.

Root with Magisk and use Advanced Charging Controller (acc) module.
https://forum.xda-developers.com/t/advanced-charging-controller-acc.3668427/
Or use old USB charger with the ampere lower, like 2.0A or lower.
That is achieved with slower charging.
PC USB socket most likely will charge VERY slow, to the point that you want it to charge faster.

You will likely need to buy chargers made by Xiaomi if you want even faster charging.
Some technologies will need to match if you want them work at fullest.

Oh I had this magisk module on my Oneplus 5T. Guess I will just download that and its app. Do I need to do anything to make it work like you are saying? I thought it only regulated charging speed for V and temperature.

Yeah this charger is supposed to be legit. Will wait and see when I get it.
Just like the Redmi Note 10 Pro and Poco X3 Pro, among other Xiaomi phones, the Poco F3 battery supports 33W Mi Fast charging and the phone ships with a 33W adapter and a 3A-rated cable.

It has the ability to control and lower the current (unit in mAh default). To make the current controled, you apply the set current and then reboot.
You can read the README in github for more info.
You have to test it though, I can't.
Use app Ampere to confirm the charging speed.

I have successfully charged my device from 0-100 in 18 minutes record. But that fried my battery within 15 days.
Had replied some similar questions.
Some info may be useful to read:
So what is the best android charging habit...?
So I bought POCO X3 Pro earlier this month...So I play games on it mainly and the question is which kind of charging habit is better? 1.Frequently charging to make the percentage between 50%-100% 2.Charge it to 80-90 and try not make to make it...

As correctly said by pl1992aw, I use an old 1A adapter that goes from 20% to 100% in under 5 hours.
With the same strategy my Tab Note 10.1 (not 2014) still has a working battery although it's of no use anymore..

Hahaha that's really overkill I don't want this kind of treatment.
Also charging speed changes based on battery percentage to make battery last longer
The idea with a low power charger to extend the battery life is really nice, cause i usually charge my phone over night and don't want to stress my battery for nothing.

Yeah nobody should want this. I used to mess in the kernel & alter the charge controlling voltage & current values. Soon I realised and concluded that charging a lithium battery with high voltages(9v fast charging) or high current significantly degrades the life of the battery. In addition, charging the battery upto 80% increases the life of battery by 4x in comparison to charging it upto 100%. Phone brands play a trick on us keeping their planned obsolescence marketing in their hands. Now I happily charge my phone with old 1 amp charger. It does slow but the battery wear data is really satisfying.

To add, fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
