[Q] Battery testing

I've read in a bunch of other threads that people are getting awesome battery life out of their Z or G2. Mine is okay-ish. I had a hero before which seemed a bit better. there are a couple of odd things I thought I'd check tho...
First, the keyboard backlight turns on and off at seemingly random intervals while open. Anyone else got this?
Also I've seen screenshots of the battery use screen showing how much power is used by each system. The screen always is at least 75% on mine, even when its been sat in a pouch most of the time with just a couple of messages or a phone call- this seems quite different to other peoples experience.
Is there any reliable way of benchmarking the battery to check? If not, does anyone fancy helping me test?

im actually suffering from the same problem,
i thaught it was because the first week i was using it lots thats why the battery wasnt lasting long, but on monday morning with a full charge ,
only with a few calls , texts and checking train times on TFL , by the time i got to sleep that night the battery was on 30%
I was shocked , checked the battery useage meter , everything was below 5% except the screen which was was on a shocking 80%
I Then formatted the phone , restored to default , removed everything ,
set the brightness to lowest useable which was just above the 'o' on 'ok' in the brightness screen let it charge to 100% for use on tuesday.
Tuesday - Morn before i left for work it was on 100% , the only thing i had setup on it was email, brightness on low - but useable .
Screen must have been on onliy for 20 mins throughout the day
Got home , battery was on 45%
battery useage - again display was taking over 70% of it when it was hardly on .
I am RMA'ing this one tommorow
I think its an issue internally with something shorting on the display, battery shoudlnt be draining that much if its not on
Out of interest was yours a UK Desire Z ?

Yep. This sounds exactly like my situation in every detail. I couldn't believe reports from other people saying their batteries were at 92% after 12 hours- even without using mine at all this wouldn't happen.
Mine is a UK desire z, from play.com. I think its over 14 days so RMA might be tricky, although I know I have lots of rights thanks to distance selling regulations. Hope I can exchange without too much fuss.
Ooh, just thought of something. When I set the brightness really low on mine (below 20% or so) the screen flickers slightly. It's most visible on a totally white page. Does yours do the same? Faulty backlight maybe?

Just tested mine, definitely no flicker.
Now my experience with the battery....
I play about half hour - an hour of games every day, plus about up to an hour wifi, using the xda app throughout the day using data, 10 - 15 txts and a few 1 - 2 min calls... Not too heavy usage.
I'm getting 30-36 hours, I'm happy....
BUT..... I have not plugged in through mains once yet. I read that charging through USB gives better performance... so far that is looking true.
I got the same kind of time out of my Hero using mains but that was with zero game time.

yes! pizza65 , i noticed the flickering too! , i thaught it was just my eye being twitchy ! Noticeable on internet browsing on low brightness! .
Mine was from handtec .. (amazon delayed too much) so changed last min,
it comes with a 2 year manufacturer waranty i think so even if you take it up with HTC direct they should be able to help if play dont.
I tried a diff radio and rom , but it made no difference.
Maybe the UK batch is still faulty , wasnt that the reason why it failed google testing and got delayed for release here?
Whats your hinge like ?
ddot what network are you on ?
same to you pizza65?
im on 02 , i dont think it is a network radio issue with switching of hspda/3g to 2g signals as it does say cell standby battery useage is around only 6% , but then again the phone could be false reporting

Not really if you want realistic real-world results with data connectivity etc. It varies too much since everything counts like signal strength.
You can always just turn off everything and burn the battery with a movie but first thing you should do is a few dozen full discharges before you do anything. I've noticed that HTC (and other manufacturers too) pre-use their batteries ie. charge and recharge them until they're optimal for consumers, hence the whine about bad batteries when people buy new phones (and in reviews as well).

I'm on Orange, I don't think its network because, as you confirmed, the "battery use" screen says that the screen is draining all the power. If nobody else gets a flicker on low brightness (it can take a few seconds to see it, but once you notice it...) then it looks like our screens are the culprit. Maybe.
I've deleted batterystats.bin and fully charged, so ill give that another chance before talking to play.
Ddot, what percentage of the drain is from the screen on your z? Also, if you press 'display' in that menu it will say how long the screen has been on, what does it say?

I have the same issue with battery performace. I've moved to Desire Z from my old Desire which had AMOLED display. On my old one, the display taked 5-8% of battery. On Desire Z I have minimum 50%, but ussually ~70%.
After reading that some people can use their DZs like "for two days of heavy use (gaming, browsing)" or "5% for 6 hours" I can't understand how?
Comparing to old Desire my DZ have poor battery performance. But the specs tells it must be much better.
I'll publish my battery usage stats after some days. Maybe it'll be useful.

Very interesting, thanks for sharing

And a really "geek" method here quoted from cyanogenmod issue:
Comment 27 by david.j.erickson, Aug 19, 2010
Now, I was still having abnormal drain on my battery. As suggested in the Wiki and also confirmed in another cyanogenmod post, clearing the battery stats can help. I followed this procedure:
Fully charge the battery, says Full and 100% under Settings - About phone - Status.
Reboot into recovery, wiped battery stats. Phone still plugged in at this point.
Reboot into rom, checked to make sure battery was still Full and 100%.
Unplugged phone.
Killed it, used Maps on Wifi and messing around. Killed it in about 3 hours or so.
Tried turning it on a couple times to make sure it was *dead* dead. It still tried to boot, but couldn't complete without shutting off.
Plugged phone in, booted it up. It may be better to not turn it on until it is fully charged, but this is just what I did.
Let it charge overnight, next morning took it off charger since it was full.
I have noticed pretty good battery life since doing this. This morning on my bus ride in I pretty much constantly played some Storm8 games and used Listen with Bluetooth, was only down to about 82 or 84%, can't remember. This is on par with previous CM release for me.
Not sure why this rom in particular had so much worse battery drain out of the gate, and not just for me. Fortunately it seems correctable. Maybe if a few of you could give this a try and see if it improves your battery performance we could conclusively say battery calibration is the solution.

What about the flicker? Can anyone confirm that?

I have a UK (read: QWERTY) Desire Z, first batch.
I tried reprodocuing the flicker by lowering the brightness completely and looking at a blank white page in the internet browser. Couldn't see it. Maybe I wasn't looking hard enough.
That said, I'm not getting the great battery life that most seem to be getting, and the stats always show the Display as being the number one drain. HOWEVER, it doesn't seem quite as bad as you guys are saying.
Right now, it looks like this:
Unplugged for 18 hours and 16 minutes, battery at 36%
Display accounts for 41% of the drain
It has been on for 50 minutes.
(stock ROM, running an IM client 24/7, synced to three email addresses... Typoclock seems to use 2% of the battery every time as well, which seems relatively high for such an innocuous little widget)

Yeah. I have some slight flickering too, slight when low light set.
Uk stock.
I dont think high display percent is an issue too much reading cyanogen issue comments.if you use nothing but low cpu burden apps, display should eat most.
Also if i have it off, power is eaten by cell standby.
Im still hoping for a settled battery log mentioned in forums.

My 2 cents:
If I "use" the phone, I have to plugin it every night.
If I do not "use" it (nobody calls that day, no browsing or GPS (Just work!)), I plugin it every two day (ex. mon - wed - fri).
The display is always 65-80 % of the "drain problem".
Today the stats are:
7.30 am: full chargerd 100%
7.30 pm: display drains: 70% in 1h : 21m - battery at 20%
I leave automatic background gmail sync on (only daylight, I use the "Flight mode" overnight)
No bluetooth, no wifi, no gps, brightness 35-40%

No phone either.

I'm on a North American Desire Z and I see the display using 70%-80% of the battery when I have the display on for approximately two hours out of the day. I keep my display quite dim too, at 20% brightness.
I'm also running everything stock. No root, no custom ROMs, no anything.

Isnt display percentage actually the display driver cpu time eaten?its just a theoretical value isnt it, not watts gone? It seems obvious that its eating a lot as it refreshes all the time regardless of display light level.

My screen on is only 33% today, im sure its usually higher though. Maybe its due to me flashing stuff all day. Ill do a full charge tonight and report back Sunday.

Battery meter is just useless

Hi,
On my One-X battery meter is completely inaccurate. Sometimes it sits for hours on one value (e.g. 90%) and then suddenly drops (with no CPU/data activity whatsoever) to for example 80%. This results with very jerky battery use graph (attached mine). I am on 1.29.401.7 and done multiple full discharge/charge cycles, but it does not make any difference.
I have never seen such bad battery meter behavior on any other Andoid phone. Have you got similar problem?

I have the exact same problem actually.

Same here. It's as if it doesn't update the battery meter when it's in sleep (fifth core running). I suspect it's because of the T3 architecture and power management. As soon as you wake it, after maybe a minute, it updates the battery status...

Mines does it. Can sit on a %age for an age then with little use it will plummet.

@Op,
No I didn't notice such a problem on a unrooted One X and with no modifications running the latest OTA update 1.29.401.11.
Did you play with battery apps or did you modify something yourself which could cause this issue? Did you investigate what could cause it?
How long do you have your device, did you install apps? Can you provide more info about it maybe? Do you softreset your device?
Did the problem exist when you bought the device?
Thanks.

So it must be general problem then. It happens to me not only in sleep mode, but when browsing the web, etc.
I think these sudden percentage jumps and meter inaccuracy also contribute to all these battery life complains from various people. I was personally shocked when after a few minutes of web browsing battery dropped instantly from 30 to 20%. It looks like crappy battery, but in fact seems to be just dodgy meter...

I have got the phone for almost a week now and I am pretty sure this problem has been there from the very begining. I initially though this is because a couple of full charge / discharge cycles are required to calibrate the meter, but it did not make any difference. My phone is not unlocked, no mods or battery apps. I did not try soft reset though.
It looks to me that meter is somehow not updating during the sleep. When device wakes from sleep, after a couple of minutes value drops significantly. This problem is probably a reason for various false claims that One X does not consume a single percent of battery during the overnight sleep.

Yeah, i have the same thing. Sometimes my battery drops about 2 or 3 percent at once, sometimes 10 percent...pretty annoying.

Thanks for your reply.
I'm new to Android but I do have some Windows Mobile experience.
It's weird to me seeing people having such problems because I realy don't experience it.
My battery meter is constant, also after a night sleep.
Maybe it's because I use my device different as others I don't know, it's strange to see all these reports in XDA forum as the One X to my opinion is a very cool device.
Maybe you could try some battery percentage apps and see if it realy is that insufficient?

I used your excellent ROMs on my HD2 in dark WM6.5 ages . I am glad to see you here with One X!
I installed Battery Meter Widget and (if the readings are correct), my One X consumes about 10-15mA during the sleep with Wifi and 3G on. I will keep an eye on the percentage.
Don't get me wrong - besides of erratic GPS and dodgy battery/power management problems, I really love this device.
I really wished that international One X version was based on S4 SoC (superb GPS with GLONASS and great power management as S4 is a 28nm chip). It is such a shame that dodgy Tegra 3 ruins this excellent device...

Hello, maybe this behaviour is only due to the voltage sampling/display ...
Someone here says the native battery app was only at 5% precision at display
and it looks like it updates in long time samples too ( 5 minutes ? ) ...
Knowing that Li-Ion goes from 3600 mV ( 0% ) to 4200 mV ( 100% ),
it means 600 mV of voltage variation from empty to full, with 1 mV precision.
So 1 millivolt is 0.2% of battery charge.
The display should be really more precise if all voltage precision was used.

looking at that screenshot you have posted the sudden drops appear to be perfectly aligned to the 'screen on' or 'awake' periods so the most likely (and obvious) cause is that using the phone causes most battery use. I have seen this with many phones, I think its normal. Being in standby doesnt use much power at all but lighting the massive 4.7" screen and running a quad core processor does, so when you use the phone it uses loads more juice... thats my analysis anyway

No, this is different. Drop in fact seem to be related to wake up from deep sleep, but the point is that this drop is massive and instant i.e. battery instantly drops from 30 to 20, bypassing all other percent states in between. Also, I am sure battery state does not update properly in deep sleep in many cases. At some point I left my phone for almost a day alone (wifi, 3g, Gmail and exchange sync, etc) and it did not lose a single percent, but as soon as started using it I observed instant 20% drop.

And I have even worse problem, can anyone help me?
Take a look at my thread (not highjacking yours, just want some help too), my current widget never reads a real value AFAIK.
It stay with -850 for more than an hour at times...
And my battery life is dismal...

So this means that seeing no battery discharge throughout the night in sleep mode isn't due to excellent power saving feature of the companion core but is in fact poor battery meter?
And yes, my One X shows fast and huge discharge (3-5% at once) when I use after being in long sleep mode

I think it too. Phone on sleep with data and sync on for 1 or 2 hours and % don't change. Use it for 2 min. and it suddently goes down by 5/10%
In my opinion the battery meter lacks of accuracy. This brings to inaccurate real time current calculations and wrong information about what's consuming power when we use it. That's bad!

I'm also seeing these big drops. For me it seems to happen between 100%-60% battery, battery level will drop anything from 5%-10% chunks at a time. After 60%, it does seem to be more stable and drop in 1-2% increments.
I've recalibrated the battery through CWM a couple of times but still get this issue.

It almost seems like there's a bug in the code that is causing the fuel gauge to not update.
I can tell you this, I modified other HTC phones battery driver. The nexus one driver for example updates volt, percent, temp, every 50 seconds while the screen is on. When off the sample poll changes to 10 minutes per update. This is real easy to see in the driver code, and you can filter dmesg log for "batt" and see the time stamps do in fact match this.
But the one x looks to be getting hung up on that part. Anyone know if kernel code has been released yet?

Low precantages of battery last much longer (without power saver)

I've searched the internet for that problem and found nothing so I'm trying my luck here.
My battery precantages is not linear at all.
When I'm discharging the phone from 100% to 0% the precantages drop really quickly until 5%-9% (Disabled battery saver when cross 15% of course) and then the precatnges seems to stop draining and every precantage last longer and longer until it gets to 0%.
From 100% to 0% I've got 2:45 screen time in my last test but between 100% to 5% it was only 2:15 screen time!
Meaning that every precent lower than 5% last 6 mins vs. every precent above 5% last 1.35 mins.
It's very annoying and happened to me also on unrooted ICS and then on unrooted JB and also on every rom-kernel combination I ever tried after I rooted my phone. (ARHD, OrDroid, Maximus, CM10.1, Renovate + NCX, XM, Komzik and stock of course).
Do you think its a hardware issue? Do I need to replace the battery? Or it's a common problem of HTC One X?

It's not a problem, it's a feature.

How's that a feature if power saver is off? Don't get the idea. I prefer that every precent will be equal. It decreases screen time alot if you don't reach the last precents. By half an hour! That's absurd.
Every precent can be 1.65 mins of screen time and by the time I will reach 10% I will have 2:28 screen time instead of just 2:10.
If it's really a feature so it's a bad one, How I can disable it?

The file is deleted when the phone is charged.
The file has nothing to do with the displayed battery percentage remaining.
Deleting the file manually is a pointless thing to do.

So if it has nothing to do with my problem what does? I already installed various of roms with various of kernels and the problem persists. I have already full wiped everthing for too many times. Maybe it is an hardware fault of the battery indicator or somthing like that?

A ROM or kernel won't change it, the battery itself indicates what's remaining. I guess the lookup table or whatever is not well calibrated for the cells in your battery.
Get over it, it's not a big deal, you can't fix it other than replacing the battery, but that's not guaranteed.

To me, any HTC One X that lasts about 6 hours with 3 hours of maximum screen time has a hardware issue.
I have similar problem ever since I bought the phone last May.
Just by looking at http://forum.xda-developers.com/showthread.php?t=2156311 makes me wonder what the hell is wrong with the phone itself.

So most of the One X's that I know are borken. I know 6 people that never pass 3hr screen time with their phone. and in XDA I see 7hr screen time and can't believe it, even if I turn off all the sensors like GPS, Bluetooth when not needed it's not helping me to pass the 3hr...

Yup! Turning off all sensors, GPS, data doesn't help.
When one turn off the screen at eg. 70% then turning back the screen on after an hour of sleep time, it will drop to 65% or worse. Always made me mad when that happens.
Even any battery saving guides like getting rid of wakelocks doesn't help.

I usually get 5 hr screen time but depends a lot on what you do. 3G data drains battery faster than WiFi, GPS doesn't drain battery unless an app uses it, etc.

[HELP] LG G4 battery percentage jumps

Title. H810 no root.
I'm aware the battery life on this one is not really good. That in mind.
-Example, (nothing running on background, everything but wifi off) using it normally until 14%. Pushed sleep button.
-Turn screen on like 5 mins after and it was 15%, used it a bit then again screen off.
-Turned screen on about 6 minutes later and it was 5%.
-Drained it to supposedly 1% then phone turned itself off.
-Turned phone on again and it was 2% and stayed like that for 10 mins while scrolling twitter with 30% brightness, until it turned itself off again and this time battery is to low to turn on.
Tried factory reset, draining till absolute 0% then 100% multiple times but so far nothing works.
Battery's health is good and factory original, no water, no heavy drops.
Let's say i root it (as far as i know its possible in all models), question:
Is there a way to push battery stats to make battery readings accurate?
Or what do you suggest? thanks.

Hi,
What you have is normal.
My owen device jumps frpn 12% to 15% after heavy and log use, thats normal, cause battery is cooling down/pre-ucomputed Energy is not consumed and Battery is calculated new.
The other Jump from 15 to 5 thats somthing you should watch closer. did that happen often?
all in all I have a sugestion but answer this first.
How old is Battery and usage time? (heavy or Soft? SOT? and so one)
Battery readings denpend on the Kernel. You are Stock i think?
Titan Kernel gave me awesome Display Sdreen on Times but battery is jumping too.

Thanks for replying!
Well thats one solved, it wasnt a sudden jump but rather a few minutes discharge doing nothing at all.
Battery is as old as the phone, 2015 and usage, i dont know for sure since it's an import US carrier phone sold to me locally, seems like it was a test phone like the ones you can try at stores. I would say battery use isnt any different than it would be in a daily usage and even if not, would be very rare for a li-ion battery to degrade in such a small amount of time. Gonna ask the seller.
Another thing i notice is very fast battery drain while playing music. I listen to music from home to work, like a 1 hour trip and when i got of home with 81% when i get to my job im at 68%.
And yeah stock everything with android 6.0, as i said currently not even rooted.

I would say battery use isnt any different than it would be in a daily usage and even if not, would be very rare for a li-ion battery to degrade in such a small amount of time. Gonna ask the seller.
Another thing i notice is very fast battery drain while playing music. I listen to music from home to work, like a 1 hour trip and when i got of home with 81% when i get to my job im at 68%.
And yeah stock everything with android 6.0, as i said currently not even rooted.

Sounds as if the Battery has some Altered Issues. How Often do you charge?
with Music You meen Mp3 or stream? (stream drain battery much faster)
Try custom Rom and titan kernel if u dont need stock services, otherwise rootand use greenify or other.
on Stock i Had SoT of 2 hours max. now i am back to 3 Hoeurs (i´m heavy user some days...)

Already using greenify. Charging 2 times a day, 1 before going to work, 1 when i come back, plugged while using it.
MP3 from stock music app, since i read somewhere a 3rd party music app caused an user a battery drain-
H810 has locked bootloader, do you know any flash tool?

Greenify is much better with Root
first you must unlock your Bootloader.
there are 2 Otions at the moment. Official (don´t know if possible for H810) and USU by @steadfasterX
for second:

read and choose for yourself if that is what you want

Just by a new battery. Original battery can be found for about 8$ at least here in Sweden..

I believe this is normal.
My H815 had it with both the original and a new battery. It used to be really bad when you charged it to 100%, restarted and it would drop immediately to 80%.
Also, especially on stock LG stuff (the graph on custom ROMs seems to be smoothed out), the battery graph was a mess of random spikes and dips

Is this normal ?

Had this for 2 weeks basically same stats why does android take so much battery?!? Standby drain is horrible. I'm on latest update. This has been from the first day I got it.

My battery life is almost the same

I'm in the same situation, horrible battery performance, I have the Exynox SM-N975F

30% is a lot.. Go for battery setup and try to find an reason (some apps maybe eat little bit more, then they should). Second problem is processor... Owners of Exynos have bigger battery usage, then Snapdragon users, that is fact. Maybe try to turn off voice activation of Bixby.

Another night, another 31% drained. From 60 to 29...
I killed all open apps before going to bed. And still...
Battery usage shows nothing. The game was played before going to bed, so it was not the caused.
This is a big disappointment.
Edit : yep, just noticed I had Bixby voice wake up enabled. Just killed it. Let's see tomorrow.

I was about to make a similar post asking for help. To me it doesn't seem right Android system is using 2-3x battery than any other app/program. And lost 13% in just one hour.

I installed CPU Spy and my Phone never ever entered Deep Sleep. 0 seconds
I've just reset all network and system settings but it seems done anything to the issue.
Really want to avoid factory resetting...
I feel I returned 10 years in time, getting back to troubleshoot deep sleep and wake locks on Android 2.0... But now on a 1K device. Shame on you, Samsung...

Mine sleeps like a baby 20 min runtime 18 min deep sleep
I have the exynos version

Running US version mine uses about 2% overnight sometimes less

Mine Exynos looks so . The Battery can better, don't know what I do wrong

I have the same results. 4hrs, sometimes barely 5hr of SOT
Android system, and idle device seems to drain too much battery ... I'm disappointed.

Yeah me too,
I see a lot of people with crazy SoTs that go beyond 7 or 8 hours. And i'm stuck here with 4 to 5 hours. I don't see why since Samsung develops its own Exynos platform. Maybe Android isn't fully optimized for Exynos ?

My Note (Exynos) use about 5% max 10% battery over night. Always on display is off and Bixby still off. 10% if everything is turn on.

Any solution to this guy's? Its driving me crazy brand new phone with huge battery drain problems...

Nope. I think it depends on the LTE band and provider. is just a guess.

I have finally fixed my problem. Reset all Network and System Settings (without factory reset), put all the settings back how I had before, and now it is going fine into Deep Sleep overnight.
Went from 31% to 5% battery drain in 8h sleep. Now its perfect.
Don't know exactly what was causing it but it must have been a bug as all the settings are exacly as I had before.

Thanks will test this out.:laugh:

Friends, I have 5 charge cycles with this equipment, I suffer from battery drain too, does anyone know what the battery health means in the "PHONE info" for samsung APP? the Battery Health value that appears to me is 40.1%. Is my battery defective?
