Annoying battery problem - Xiaomi Poco F1 Questions & Answers

Howdy! A few weeks ago I noticed on my phone that the battery did not last as long as before. I said it would be from the software and I decided to reinstall it. First, I switched to a custom ROM (Pixel Experience) and there the battery life was even worse. Then I went back to stock ROM and it seemed to work better, but the battery was still discharging too fast.
I put an application for measuring battery life (AccuBattery) that told me that my battery (one year old) was at 79% life (3100 mAh). I replaced the battery with a new one. Surprise! And with the new battery still at 79% life it says it is. And the same 3100 mAh maximum capacity. I tried all kinds of methods, all kinds of custom ROMs and it all works the same. What could it be? Has anyone had a similar problem?
Thanks!

Nope. No issues with mine. You said you changed the battery, so you opened the device? I'm not inclined with HW too much, but since you've tried the most drastic solution software wise (flashing custom and MIUI ROM) then it could be a hardware issue by this point.
Again, not a hardware guy, but maybe there is a loose wiring or connection (to the battery) or maybe a short-circuit. If you need further help maybe ask help from a repair guy. But that's just my take (possible hardware issue)

[Q] Any one else have this weird battery drain?

I got my galaxy s2 (international version) about 4 months ago. Recently I've noticed some weird battery drain mostly when I restart my phone, but it happens other times just out of the blue.
It might be a software bug not showing the proper battery level, but I've attached pictures that show normal battery drain even after that jump down. Obviously, if it was a a software fault the battery percentage should remain level or go up slightly. (Yes the battery level does go up a bit, but I lose significantly more battery than I gain.)
This has happened in many instances and I've only got a screenshot of two. Sometimes I get big discharge and at other times its small. It's pretty annoying when you think you've got enough battery and go out, only to find the phones dropped 20-30% out of nowhere.
My phone is unlocked and not branded (bought from carphone warehouse UK- CPW). It's running stock XXKI4 firmware (2.3.4) and I'm not rooted.
So my question is, has anyone else seen this happen or have I got a faulty battery? Is there a fix?
Hi there,
Battery drain is one one the main argouments you can find in this forums. ATM I'm in your same condition: after latets ROM ugrade (I've got latest CheckROM release), my phone "sucks" al lot more battery than before.
A lot of things could affect this: themes, skin, kernel, application bug, bad battery checking and so on. There isn't a valid answer... I think you must indagate on yourself, comparing what you find with forum's infos!!
Good luck!!

There are several threads about battery drain.
For example here => http://forum.xda-developers.com/showthread.php?p=16973603
Maybe you find a useful tip.
You have always test it on your phone under your conditions.
You can try to flash special (Custom) ROMs and kernels, which are optimized for better battery life, but as there are so many different influences on battery life, it is nearly impossible to find a general "fix" for all users and phones.
Good luck!
well at least yours lasts 15 hours, mine lasts at most 10 hours on heavy usage.
P.S. I am using 2.3.5
As to Anwser to those "drops" or "gaps" in the graph, just recently i noticed that my phone was working normally, i was monitoring its battery drain (i have a thread going on about it), and after some time of no using, after class, i noticed that my phone asks for my SIM PIN again, and is in Safe Mode (i dont really know what that it). When i checked the battery monitoring graph (battery info) i notice the absolutr same fall (from 70% to 40%), but i remember that i saw and used my phone at 60-50% too ! So i can only assume that the phone crashes, eighter reboots for some reason, and the data isnt saved (for example it saves the data every 2 hours or so), so there appears the "gap".
Thats simply my opinion, but i do remember using the phone at the % between the two extremes (IN the gap), so i guess the data wasnt saved.
EDIT: Ha! I'll add some pis now to show you guys this: so in my current history i have two gaps, one big, and one smaller before. So, the first time, i turned off the phone and PULLED OUT THE BATTERY aswell cause i wanted to check my batteries mAh (its 1650 but thats offtopic). Thats how the small gap appeared ! As for the big one, my phone seemed to crash and reboot while i didnt notice, because in an hour or so of no using i woke it up and it asked for the SIM PIN.
So there, i think the phone eighter crashes or doesnt manages to save the battery data, and those gaps ("falls") appear.

[Q] Battery lasts only 4 hours without any use. Problem is hardware or software?

I bought the Motorola Photon 4G in the U.S. but I live in Brazil. In the first 10 days of use it worked perfectly, had battery life of 36 hours with moderate use. After you update it to last OTA, I do not know if it was coincidence, the battery does not last more than 4 hours without any use. Already reset to factory rom, I used several methods to calibrate the battery, I installed another rom and everything remains the same. The screen and battery get very hot when using the photon. I bought new batteries and charger and nothing changed. The interesting is that even disconnected the battery completely discharges within hours. I use the minimum screen brightness, WiFi, GPS, bluetooth and data are off. Right now I have only the factory-installed app, and yet the battery only lasts about 4 hours. The Photon is not sold in Brazil, therefore, have no guarantee nor an authorized service center for Motorola Photon. From what I see must be a hardware problem, does anyone know what might be happening? (Sorry for bad english)
To be honest, I'm lost here BUT your comment about the screen and photon getting very hot, the only time I experience that is tethering and thats my last 3 devices. This is usually caused by rapid battery drain.
Although I only tethered a few times, the battery was, more or less, programmed, even after I stopped. I ended up buying 3 new batteries. Cannot remember where, but they were under $10.00USD (CellPhoneShop.com)
I definitely recommend you make sure your not tethered.
But have you tried a wipe/SBF?
If an SBF doesnt fix it its probably hardware.
Thanks for your help. But I find it very strange the battery discharges even when the device is off. Telephone operators in Brazil use GSM only, so the phone may be trying to find CDMA signal, but do not know how to avoid this.
Previously had installed the SBF "SUN-198_7" and nothing had changed. Now I installed another SBF (SUN-154_5) and despite the battery lasted a little more, still has low life. I'll try another SBF or other roms to see what happens. Then do I comment the result here.
After the sbf to 154-5 does the battery still get hot? This sounds like a bad battery. I'd try replacing it...lest we read about you on engadget or gizmodo in one of those exploding cell phone battery stories.
Have you looked at this thread yet?
http://forum.xda-developers.com/showthread.php?t=1265816
After much searching, I discovered that the problem is hardware. I applied a SBF (SUN-198_6) to relock the bootloader and the root. I think it worked. I'll send for assistance technics, will they know that I unlock the bootloader and the root? Because if they find out, I lose the warranty.
I've had a major battery drain issue in the past which was due to a specific app that was just heating my phone up and somehow not jiving with the with the software (Widget Locker)... I disabled it and battery went back to normal. Also, since then the dev corrected the problem.
Did read several comments about the drop in battery life using the Widget Locker. However, in my case the battery is also drained with the device (Photon 4G) off. Even in Airplane mode the battery lasts a maximum of 5 hours without any use. I've tried everything, Factory Data Reset, other custom ROMS and even two other batteries, and nothing changed. I applied a SBF (SUN-198_6) to relock the bootloader and the root. I'll send for assistance technics, will they know that I unlock the bootloader and the root? Because if they find out, I lose the warranty. Will I have problems with this?
Also it sometimes helps to charge full and recalibrate the battery...good luck!
you might have overclocked your processor, try download setcpu and check bring it down to 1ghz, another problem might be dust inside the phone try taking out the battery and cleaning the inside of the photon with a dry paper towel

battery consumed fast since update

My samsung galaxy s2 has some inconvenience issues to be solved. Since last month ago it begin warning high voltage when charging the turn-on phone. Then it would stop the charging the battery . It can be charged only if I turned off the phone and turned it on when it says 100%.
Not sure whether was the battery go wrong and its battery life already very crappy, and the things even worse when the phone was upgraded( it drained a lot as constantly searching for 4G). In fact a few weeks before, I asked help from friends borrowed his MPJ spare battery for this battery issue. His replacement battery was better but why Sprint and Samsung know this is the major complaint but still have failed to correct ever…
I also have been to store but nothing is solved unless to pay to have it back to repair. then I have to begin purchased extended batteries(one even have much higher capacity at amazing 5000mAh) and chargers followed with the friend who helped me so that i keep several charged and ready to change out as needed. but i still wonder anyone know why it would warning the high voltage and it did not appear again after changing batteries?
Could be the battery, but you fail to mention which version of the S2 you have (assume you have the i777) AND what you upgraded the firmware to. If you did a stock OTA update and you're not rooted, there's really nothing anyone can help you with other than suggest a new battery.
If you're rooted, I would flash a different rom first before investing in a replacement battery.
If you decide to get a new battery, I recently bought this one for $5 and can vouch for it's compatibility (minus NFC, which has never really worked properly for our phone anyway).
You will find after a fresh flash most roms will seem to consume more battery than it used to. Give it a few charging cycles before you decide that your battery is bad,or the rom, or the kernel is bad. It may need to settle in a bit.

[Q] Original ROM: GPS broken, weird long battery life

This one is a weird one...
About a week ago, I needed GPS to navigate out of a town - I waited and waited and didn't get even any satellite reception... It turned out that I found the way by myself and just closed the navigation. A few days later, same situation, no visible satellites at all... Didn't have time to reboot the phone, so I just closed the navigation and went my way.
Now, something weird is going on with my phone... Usually I get about 2 days of battery life - but since last charging, it looks i will get about 4 days and I have been using quite a few apps, browsed the net, made SIP phone calls, made normal phone calls... (more than normal usage for me anyway).
Is it just me or are those two things connected in any way? Can it be that GPS has crashed somehow and in the result, lowered the power consumption of the phone? Is it possible to turn off the GPS 'on demand' to extend battery life?
All other stuff is working like a charm...
I am using stock ROM (4.1.2, radio: I9100BULS1, build: JZO54K.I9100XWLSD)
Why do not you try installing a different rom see why.

Well, a colleague of mine has the same phone and has experimented with various ROMs - none gave him so much more battery life. It is not the question of which ROM is better in terms of battery life, but whether some weird (non-functional) state of GPS (I have it normally disabled almost all the time via drop-down menu) can cause the extended battery life. And if this is possible, can this be done on purpose?
The ROM stock give many problems, you're not in fact the only that the strikes. I advise you to try some Sammy Rom! JellySNAP v6 and, for example, a great ROM based-stock Sammy

I am bumping this topic to continue the discussion...
I am aware of other ROMs and have experimented with a lot of them on another phone. Due to extensive set of installed applications, loads of data and relatively stable stock ROM, I haven't really taken the time to do the transition.
So, I am not really looking for a solution to fix GPS, but the opposite way. I want to know if I can break GPS on next boot in order to obtain such long battery life... How many days of inactivity do you get with non-stock ROMs? At the moment, I am getting 5 days of light use WITH stock ROM (WiFi, Bluetooth, data disabled, only connected to mobile network to accept and make calls). I was never been able to do more than 3-4 days and my battery is now over 2 years old....
So, please, don't try to persuade me to install other ROMs by stating that they are better and more stable - list your battery lifes in case of light use or inactivity.... Do you get 5 days on 2 year old battery?
If you think breaking GPS is somehow responsible for greater battery life, you're going to end up rather disappointed. That concept defies logic given GPS only uses battery when you're actually using it. How is it possible for battery life to somehow magically double as a result of GPS being 'broken' ?
Thus far you've not provided one duplicable 'test' that other people can try to see if they get similar results, and all you've done is blabbered nonsense in a couple of posts. I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ? I know I'm not, because trying to put that stuff back when your silly theory doesn't work is a pain in the arse.
Did it ever occur to you that given the battery is two years old it's quite probably on its last legs & is very likely chemically unstable (this is why 'old' batteries swell up & sometimes even burst). This instability might be causing the extra battery life as the battery approaches the point where it's no longer useful. Put it this way, that's far more likely than busted GPS causing the extra battery life.
So, please don't try to persuade us that breaking GPS somehow doubles your battery life with a 2 yr old battery. Logic & almost 3 yrs worth of different people's experiences on here with this phone just don't support your ridiculous assertions.
That was a spicy reply, MistahBungle
Some facts:
- No system update was installed in the last month
- No application has been removed
- System hasn't been rebooted for a month or so
- Never got more than 2-3 days out of battery in idle
- Battery is 2 years old and is physically not damaged or swelled
- GPS isn't working (not even receiving or predicting a satellite on a clear day)
- System is rooted for a year or so
- Battery lasts 4 days now (instead of <2days a month ago)
- Connected to 3G network (no data connection)
I would try to reboot my phone, but I am afraid that it will all be over...
So, to stay with firm facts - how much battery life do you get with alternative ROMs in real life? Is 4 days (5-6 days with new battery) something usual?
That concept defies logic given GPS only uses battery when you're actually using it.

Can you then explain me the difference between Cold and Warm GPS start? As far as I know, phone tries to keep as accurate GPS time as possible and a bunch of ephemerisis data in order to decode GPS data faster, next time you enable GPS. This defies logic that GPS is completely OFF when it is 'disabled' by GPS button in Android system.
I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ?

No, I don't expect it to. I am looking for information whether anyone experienced anything similar.

In Lithium-powered batteries, I haven't come across the fact that battery capacity is increased with battery ageing and sweling up... On the contrary, internal resistance goes haywire and capacity drops, contributing to even more heat being spent internally by the battery and speeding up the process of degradation...
I may have not been cooking my own ROMs and writing drivers for phones, but I have quite extensive background in embedded systems and electronics. Battery life can not increase just by itself - there must be a reason... My lifestyle hasn't changed, my environment also didn't change, other phones at home didn't experience such battery life extensions... The only thing that I noticed is that the GPS is not working. I opened this topic in order to discuss whether that's the true cause or not.
So, based on '3 yrs worth of different people's experiences on here', what could be the cause for such prolonged battery life? How can I debug it by myself without rebooting the phone?

[Q] battery callibration..myth or necessity

hi all
i flashed neatrom kk and then cm11 recently
but my poor 3 years old battery giving nonsense replies
it drop down from %80 to % 12-14 sunddenly after a reboot or crash
so is this because of my battery condition? or because of flashing roms?
and can callibration makes a differ? or is it just a myth?
ty
3 yrs old battery is the root of this problem. Flashing roms may affect your battery life but it happens only when you do it too much.
From my personal experience I can say that battery calibration is more a myth than necessity.
Im having the same issue. The best option is to buy a new one i presume
Correct. And calibration is an absolute myth. It's impossible to (re)calibrate these batteries.
There's a "Reset Fuel Gauge Chip" option in Dorimanx kernel and it stabilized my phones battery. It used to show 30% after a restart just right after i unplugged it from the power source:good::good:
