Extreme battery drain - Huawei P9 Lite Questions & Answers

Hey guys, recently I've been having a TON of battery drain. A while ago someone replaced my screen since the I dropped the phone and the glass broke(stupid me). My friend and I thought that maybe that guy also replaced my battery, without telling me. But what mostly happens: When my phone is on like 50% (sometimes less, sometimes more), it shuts off. When I restart it its at 1%. I added some screenshots off today where it happened again. What could be causing this? And is there anyway I can check if the battery is replaced? Also, the new glass has a few stripes under and above the screen. I don't mind in that much but does anyone know about that aswell?
Thanks in advance.

Well you could first try to reset your battery... There are several methods out there. Just google for it, one popular one involves deleting the batterystats.bin file.
There are also apps that show you the battery health. If it is poor, it is likely that the battery is just damaged or drained.
I used to buy second hand devices, to check the battery I usually read out the charge cycles (how often the battery charged from 0 to 100). However, I don't know how it works for Android these days. But searching for that key word might help you.

Another Jasjar Battery Drain Problem!

Hi all, i have developed this weird problem in my jasjar and i'm sure it's some settings that need to be changed somewhere and not the battery itself. When i first got the jasjar, it gave me a good 48 hours battery backup on standard use but i lost my charger and started using usb to charge it. it's since then that my jasjar drains the battery in less than 12 hours. i have tried replacing 3 batteries but to no better effect. I remember reading something about the Li ion polymer batteries having the memory effect or something and how to reset that in the bootloader mode. if you guys could help me figure it out and fix the problem, i'd appreciate it! here's the details of my rom.
R:1.13.00
G:42.47.p8
D 2.01.06 wwe
the rom is the wm6 from jwright.
(nb: i had the same problem with my shipped wm5 rom and i thought upgrading it would help but it didnt apparently).
How long do i need to use the battery to check the drain thingy. the reseller tells me to use it for 2 weeks before judging it. i'm screwed with having no battery life to this otherwise beauty of a device! if i could get any help, it would be much appreciated. thanks in advance. (josh).
Had the same problem, been happening all week, the phone would just switch of even though it registered over 80% charge. no i am happy again because i read on the forum that you need to totally discharge the battery occationally for it to get to a full charge, it appears that there is some sort of memory effect where the battery thinks it is nearly discharged, try it, i am sure you will find that it workes.

I too has a similar problem but this method did not solved my prob as my jasjar switches off by itself at 40%.
I had a similar problem a couple of weeks ago as a charge would last less than 24 hours when I used to be able to last 2-3 days.
Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

Had my MDA PRO for 1.5 years, and never had this problem. Battery lasted for 2-4 days on average, although now I have a 3200mAH battery it lasts for well over a week on a single charge
Lithium ION and Lithium ION Polymer (the HTC Universal uses the latter) do not suffer from any "memory effect". The only battery type that does to any significant extent is Nickel Cadmium, which is rarely used these days.
It's also impossible (well, almost) to completely discharge Lithium ION Polymer batteries - internal circuitry in the battery shuts down the cells when the charge gets too low, at up to 10% charge. This is because a completely discharged L.I.P. battery becomes unstable, broken (unable to be recharged), and runs the risk of explosion or leaking in this state. So don't attempt to drain those batteries completely dry folks - it's dangerous! Letting them run down naturally in your Universal should be safe though because of the cut-out mentioned above.
Maybe the Uni just has a large batch of bad batteries? You should also check what apps you have running on it all the time, and how often you use bluetooth and wi-fi - these two REALLY drain the battery if you keep them on all the time... Also try MemMaid, this is great at cleaning up your notifications queue, which is where lots of apps leave old and obsolete entries clogging it up.
I have the same problem. I do not know where the charger is, so I am always using the USB while syncing. I also tried 2 batteries, but they both last about 12 - 14 hours. Maybe it is caused by WM6.
I did not quite get this solution:
"Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

What is the solution?

btw aj had the same prob. appeared after 6mnth. i bought new battery. btw here is several threads with same prob. try 2 look for solutions there(imho its only one-new batt.)
I feel like I'm walking on eggs...I bought my Jasjar used on eBay just over a year ago, still the original battery. I almost never use the 110v charger, always a USB conection with my Mac, often recharging at 55-75%. I just intentionally ran down my battery to 18% (got warnings to recharge), and recharge via USB/Mac again. It took me almost 4 days to get to 18%, and Bluetooth is constantly on for ready use with my earpiece.
Curious: are the problems with original or replacement batteries? Cheers,

It's worth taking into consideration that when flashing, you really need to have a full battery. There are reports of batteries starting this kind of behaviour after user has flashed with drained battery, then causes battery charge issues until next reflash.
IMHO even if u charge with a full charged battery still u get a prob so i think its a common issue with the jasjar and its power managment software itself by default as lot of people with diffrent ROMs are complaining about it.
no changes...
well, folks, i tried all these gimmicks but not to any definite changes ... i guess i need to consult the service center guys at last...i didn't want to do that but i guess i need to. i'm sure it's not my battery as i've replaced 3 of them...i dont kno what else to do!!! thanks for ur posts tho as i get to try diff things to check if ma battery is doing ok...keep postin...thanks...

problem with battery?
I have the same problem, it firs appear on original battery when charge was 40-50% so I have bought the same battery model (1620mAh). But it doesn't help. Now I,m using the 3200mAh battery and it doesn't help as well. The thing is that XDA switch off it self always on deferent charge level (sometimes is on 20%, 45% ar 80%...so is very difficult predict when it happen again). And one more thing...when it switch-off and I try to switch-on back, I can't (keep switching off), only slolution is put on charger!!!
I have downloaded the service manual (I think called "confidential") and it mentioned that it could be a problem with main board (so its HW problem). So can anybody tell me is a problem with bat or MB? (replacing the MB is fcjfdj$#ing expansive). Thanx.
well if your XDA does not switch on until you start charging it that's a clear indication that your battery is empty. I have the same with my faulty battery. Replaced it by a working one and it's fixed. Something is definately messed up with the charging circuit or the batteries though. They are not supposed to die so easily.

The first time I flashed the PDA I ruined my battery. This time I thought I'd be smart and I put in the old battery while flashing. After flashing I put back the new battery and now that one is broken too! It wasn't even in the PDA when I flashed it. How bizarre is that?
I have to admit I did not fully charge that new battery before flashing, but I figured it would be safe since it wasn;t in while flashing. The battery worked fine the day before I flashed my phone (got the "charge now or save your work" message), but after the flashing and putting it in, it just crashes at around 30% or 40%. The usual battery misery.
Maybe I should try fully charging it and then flashing again. Trouble would be how to get it fully charged though. I always felt charging cuts off early on the "broken" batteries (pull the charge plug and stick it back and it charges for a while again).
I managed to restore my battery to good health by completely discharging it in bootloader mode.
First I completely charged it. When the led went green I pulled the shcarge cable and connected it back again. After doing this a few times it doesn't stay orange so long and then I stopped and left the cable disconnected.
I reset the phone (on full battery) and then I set the unit to boatloader and waited for it to completely discharge. I reset the phone again (on empty battery) and low and behold my trusty "charge now or lose data" warning came back.
BTW I reset the PDA hoping maybe it would store the power levels. I remember that trick from my Palm days where sometimes you had to reset a PDA on full battery to calibrate it.
I charged it back to full capacity and started using the phone as normal. When the battery was empty I got no crash but a friendly warning telling me my battery was going low. Phew.
Will try the same with my other troubled battery over the weekend.
I have the same Issue.But , I think it's about Rom.
and I'm try a lot of ROM version ,only one Version canbe use more than 3 day.
I can't find any reason ,.
discharge in bootloader ,I do it ,But battiery is same time for used.

Unidentified issue after Reassembling

Hello i got an unidentified issue with my Touch after reassembling it.
I bought a White Cover for my Touch and everything worked fine on disassemble and reassemble it. But now i got this crazy issue with my batterylife. It is not normal, the life is so shorten up to some hours without doing anything.
When the mobile phone is just idling the battery life is after 2 hours from 100% to 60% down and after 6 hours my battery is empty. I don't understand why this happen.
Could i do anything wrong on the assemble? The other thing is, that my camera stops also working after this reassemble. I can start the program but nothing happen. Tried many reboots and also formating system and installing it again.
Camera is still not working and something eats my battery
Does anyone have ideas? Thanks in advance.
Greets

When you try to start the program, does anything happen? Does it launch the program and display a black screen as if the lens was blocked, or the camera chip is not plugged into the main board? It may have become disconnected during the case swap.
As to the battery, it could be linked, it may not - I don't know I wonder if something could be shorting internally afterwards, but I wouldn't be too sure!
How old is the battery as well - it may well just be coincidence that it has come when you changed the case (although I doubt it!)
When i try to launch the program nothing happens. It doesn't show anything just idle, like i would have never clicked to open it.
I will check today again the camera at the mainboard, when i will arrive at home after work. Maybe it is this problem, that camera tries to connect and can't and eats my batterylife.
The battery is about 2 1/2 years old but worked fine before i changed the cover my phone was many days on before it gone empty. It's just curious
Now i need always the charger for my phone every some hours
Damn, i tried reassembling it again but it didn't solve my issue. My Battery is still shorten empty and camera is also not working after reseating it.
Hey stu any other ideas? I have to recharge my phone 4-6 times a day, this sucks really.
Do you think it could be caused by the cover? That maybe a piece of metal is sucking my battery out?
Recharging of my battery is also low now, it need soooo long. Please need help.
I really am still tempted to say the battery is dead.
it could be worth installing HomeScreen++ (UI) so you can see how much charge is being drained, and also how much goes in when charging.
it may be possible, on a long shot, that the battery is not passing enough power to boot the camera - who knows.
Is your battery slightly buldging as well? This is something I have noticed at my work that happens when batteries are coming to end of life - they also tend to be rather erratic and do not maintain a charge or take a charge (these are 4400mah batteries that cost £100 as well :/)
Have you read the thread in rom development as well about battery conditioning? That may help, anything is possible, right?
I took my devices apart yesterday to see if I could find something that may be shorting - but I was unsuccessful
So okey i have downloaded this HomeScreen UI and my Battery is draining 326mA/1305mW and Device is 36°C or 97°F hot. Is this okey? How much should it be?
At charging my Battery it shows +265mA/1008mW.
Battery is not bulging its ok like always.
Maybe i should buy new better battery on ebay?

Sweet jesus, my batery drain is 79mA/331mW
Something is causing some massive battery drain - What apps are you running/installed?
Stu i have normal installed programs of my ROM Onyx Ultimate 4.1.6. But it can't be any program installed, i did a hardreset and it was before the reset too like that.
It happens after i changed my Cover to White with everything except the digitizer, Speaker and LCD display them were okey.
Could this issue be caused of my Speaker? On putting it out from old Cover i broke it a little bit with a screw driver i push it to get it out and now the sound is weird the bass is warped. I ordered a new one, it still works but ****ty.
But who knows, if its not this Speaker drain so much, but why it should I am so helpless
Be interesting to see what happens with the replacement to be honest - I am really intrigued!
Not a lot more I can suggest for now - I'd still try a new battery after the speaker if there is no improvment.
How do the connections look on the speaker? Are they all clear and not touching anything else as well?
Okey i will buy a new battery for my phone, maybe its the issue, but i don't think so.
Today it is curious my phone just drain 650mW not 13xxmW anymore. But when i charge my phone, its increase again to 980mW
I will disassemble my phone today again at home and check if some metal is not correctly in the cover.
Okey i tested my phone again without the cover. I disassemble it and powered it without cover on and my battery was draining same about 1169mW.
So it is not the cover, maybe i should really buy a new battery.
Ok it did not help with the new battery. Still the same issue like before.
I bought a new mobile phone HTC desire and I am so happy about that. There is no compare with the old touch
Hmm, still trying to figure out what would be wrong if it was not related to the battery - possibly what controls it - but then that is a hardware fault.
I'll do some more thinking and see what I can come up with.
The desire is an awesome phone - one of the ones I am looking at getting soon. (Currently have a Hero as my main device and my Elfs as my spare/mess around phones)
yea desire is really awesome, i like to browsing through the market place
i think the elf has problems with the camera and this the issue for sucking battery out.
because it doesn't work anymore. when i press on the camera button, nothing happes.
no sandclock is showing up. just idle like never clicked on the button.

Two battery sizes (constant switching)

So I bought myself a second battery (3500 mAh), and as I switched to charge it, I noticed, that it already was at around 70%. As my old battery (standart Defy battery) was around 60% at the time, I switched back to charge that one instead. But suddenly the old battery was at 100%...
So my problem is, I want to switch back and forth between the two batteries, but if this keeps confusing my Defy, this might not be possible.
My question is: Is there an app or any other way to calibrate the phone so it is able to differentiate between the two batteries without having to charge both completely (only way I found until now)?
I tried to search the forums, but the only post I found was this one http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ , which is not very helpful, for my problem.
I'm sorry, if I missed a post, that might have kept me from opening a new one
Also I'm sorry for my bad english
Edit: The other reason I want to fix the problem is, that I'm afraid that I will "overcharge" the battery if the phone "thinks", that it is still at 50%, but in reality it is already fully charged.
It's probably nothing, but I'm bad at this kind of things.
Edit 2: I just tried "battery calibration 1.7" and it didnt help. Same setup: I switched from my ca 50% normal battery to my 80% 3500mAh battery, charged the big one, and "calibrated" it. The app said something about "calibrated it by 7%" or something like that. Afterwards I switched back to my old battery, and again it was at 100%, so I tried to calibrate that as well. At first, the app didn´t want to calibrate at all, so after a few restarts I tried again, and it said it "calibrated by 3%".
But it should be somewhere around 50%. I don´t get it...

Hardware/Battery Issue/Loss advanced question

Hi guys,
My had brother hard a problem with his phone regarding his battery life. He claimed it drained too quick. So he bought a new phone.
After I had "accidendatlly" destroyed the eMMC of my nexus 4 (See this thread) he gave me the phone and told me if I could fix it that I can buy it for a sharp price form him.
I've replaced the battery with a newly bought one online and got the phone out of hibernation mode by connecting it with USB cable and doing the volume down + power button trick.
I've noticed some issues regarding the battery:
- The first time I rebooted it battery life went from 96% to 84%. This was when doing a factory reset (from the menu in android 4.2.2). This has occured once.
- Last night the phone was fully charged so I hooked it off the charger and turned it off. This morning I turn it on and I notice the battery is at 66%. Literally 1/3 of the battery life was lost when the phone was turned off.
Obviously, (I think) there's a loss inside the hardware of some kind. There's one piece of history attached to the phone.
My brother had it one month and dropped it on the floor and his screen was cracked. He then let the screen be replaced by a repair center. They did replace the screen and locked the screws from the battery with some kind of glue (i think) because it was very hard to loosen them.
My questions:
- What could have caused this? Can it be by something done by the repair shop (reversible?)
- In which part of the hardware is this (loss) most likely to occur? Or one can't know this?
- Would it be sensefull to disassemble the phone and replace the screen with the screen from my broken phone (the one with the broken eMMC chip), or is there 0% chance on success by doing this swap?
- Any suggetions on how to tackle this problem or is it just something I'll need to accept. (which is hard to accept, )
Kind regards,
Semi
You should first try to charge it to 100%, then calibrate the battery (there's a little tool in the play store called BatteryCalibration). The percentage values are just approximate. Android knows the amount of mA the battery has when full and constantly checks the current as it drains to calculate the percentage left.
Calibrating the battery basically means deleting these statistic files to allow the system to start from scratch. You may need to do a few discharge/charge cycles until it is somewhat reliable.
If this doesn't help I assume the fault is hardware sided.

Hi thanks for your Swift reply. ive checked the app out and i think it needs root. This phone hasnt been rooted yet so ill Get to it when i get home. Greetings.
I do have the exact same problem (phone was never droped) - see this thread:
http://forum.xda-developers.com/nex...rs-off-charging-battery-t2701353#post57181337
Nexus 4 seems quite vunerable to this though I've not found the cause/solution for this on the web yet.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?

Battery readings going completely wild

So recently my phone (unrooted unmodded N910C) battery is being extremely weird. When I try to charge my phone, it sometimes doesn't go beyond around 70-90% but if I take out the battery and put it back in, it shows 100%. It sometimes also shuts off on its own at around 40% and when I plug in a charger, it shows sometimes 0% and sometimes 40% (but if I turn it on, it still says 0%). I've tried a lot of things, including discharging completely and recharging to 100% (powered off), factory reset, clearing cache, and quick starting battery and nothing seems to work. Does anyone have similar problems and has anyone found a solution to this?
The problem is the battery ... the catode pin inside battery is not working properly. The motherboard of the phone it just reading the voltage and temperature of the battery. Your percentage shown on status bar is based on what current intensity is received from battery. So just replace the battery... esxuse my poor english

Are you sure it's the battery? I took it out and everything looks normal, including the pins. Also, battery apps said that my battery health was good or should I not trust them at all? I just don't want to buy an extra battery if the problem is not with the battery.
I meant the catode pin inside battery not outside. It's your call if you buy a battery or not. I just writed here how the proces work because i have fixed lot of motherboard i knowing about this i have explained to you. Cheers
i have the same problem too and i tested every things and now i am really tire , i dont think thats problem was the battery , can anybody help me plz?
Had similar problem yes new battery at the samsung store the assistant said many note 4 batteries selling I got the last one. Maybe we got a bad batch or its deliberate. Maybe we could do a survey how many people have had to buy a new battery
Sent from my SM-N910C using XDA-Developers mobile app
I also posted a similar problem. In my case the problem is more alarming, because it's happening in two different batteries, one of them is rather new and fresh. It seems that it started out of the blue, I did not make any major change in the phone.
I am still investigating the issue, I'll be back with more observations.
Just an update on my situation: I bought a new battery and now the battery readings seem to be fine.
I had the same problem as you OP. The problem was definitely the battery for me at least. Bought a new one just the other week and now everything is working perfectly
If the affected battery is under warranty get it replaced for free. Or if the problem does not get solved after cross checking many possibilities. Just buy a new battery. Simple. Good luck.
