[Q]Battery life - Xperia Z Q&A, Help & Troubleshooting

Ok so I got my XZ yesterday and the battery life is worse than my SGS3. My S3 lasted 1.5 to 2 days with the same amount of usage. I have no idea how the battery life is on 4.3 or 4.2.2 as I upgraded it to .230, the moment i got the phone.
Anyways, my question is whether the battery life improves if i install custom roms (LB) or is the problem kernel sided.
Also is 7% of battery usage a lot? Google play services is taking 7% of battery.

Battery life on 2.3.5

Anybody notice any changes as far as battery life. I just wanna know because im currently using a 1800 mAh battery (lost original battery) from ebay and they don't longer then stock. If you see any major changes i might just buy an OEM battery.
I did notice an increase in battery life when I upgraded to 2.3.5. I am a heavy user of my phone on a daily basis and it last about 5-6 hours longer from my experience.
Switching to V20p showed a very noticeable increase in battery life for myself.

The battery life has improved so much, I'm not getting the extended battery. Maybe a couple of regular batteries as the improvement easily takes my phone all day. Before update, it would only last 4-5 hours with usage.
I have to agree battery life has increased by quite a bit. My wife was getting severely pissed off at this phone because of battery life and other Froyo glitches and since updating she has yet to have any issues and stopped complaining about battery drain. Ahh the relief of not having to hear about how she hates the phone and wants it replaced Now lol. Hopefully we get to see ICS eventually, not that I am counting on it anytime in the near future and most likely not at all but still it's a nice thought lol.
better definitely. Not as good as the Rogers Samsung Galaxy S Captivate battery life though. Can't believe how much that one improved with the gingerbread update.
Had anyone else been seeing strange issues on the Rogers gingerbread update Ruth the battery stats? This morning after an hour off the charger battery was at 88% when viewing the battery usage it showed 15s on battery and that the only thing using it was the display and the percent was 165% I have a screen cap to upload later to show it.

Same here. My P925 have same problem. The stock ROM and ThiaiZO3D, which I am using, are same. It always show me less than 20s even after 24h.

[Q] My SGS is extremely draining, battery weak? [cm10, sema2.5]

Hey people,
I have an Galaxy S i9000 wich is about 2-3 years old.
Since a year my battery is draining a little fast, but since a month its sick and frustrating because it last -+3 hours when using whatsapp/music 70% of the time (7 hours with less use).
Thats not nice, and I thought my battery could getting weaker becaue my phone is almost 3 years old*.
ROM: Cyanogenmod 10, 4.1.2
Kernel: Semaphore 2.5, I9000XXJVT
I don't think it's just the rom, Android 4.0 was draining also (but still better battery life in comparisation with 4.1.2...)
Now my question is, do you think purchase a new battery for the I9000 will solve this problem?
Thanks in advance

It seems that the problem is the battery itself, i would try to replace it
Had the same case as you (even same rom and kernel) and i changed the battery... now it's a lot better with almost 24hrs of battery use between one charge to another

It's possible your battery has degraded but you can install the Better Battery Stats app to get a better idea of what is eating so much battery.
Thank you, I will purchase a new battery soon. One more question, are the smartphone batteries (SKU: 59974) from DealExtreme good? I mean, this is from a Chinese wholesale site (made in China) so I'm not sure about good battery performance.

[Q] have a problem with my extended battery 5000 mAh

hey everybody
hope that you are all okay
i just ordered an extended battery with the capacity of 5000 mAh
here is its link
http://www.ebay.com/itm/New-5000mAh...axy-Note-GT-N7000-Cover-Charger-/330750349616
and that was 4 days ago.
the problem is, the battery drains so fast
for example, when the phone is idle, it may use up to 12% in about 7 hours
and if i'm surfing the internet using mobile data (3g)
it may not even remains 2 hours of continuous usage
it also doesn't stay much with display on> about 3.5 hours only
while my friend who ordered with me the same battery
its battery remains much longer than me
could it be the rom i'm using or something else?
i'm on [ROM] Sweet ROM V11 LTA 4.1.2 [October 25th]
Use battery stats plus, free from gplay, to check what drain it and estimated time. Even the ori 2500 battery does better than that.

I'd suggest that you return to stock ROM and make tests to see whether the problem is in the ROM or the battery itself.

[Q] [POLL] Battery Life on Stock LOLLIPOP

So Guys android 5.0 is here and i think most of u have tried it.So hows Battery performance on lollipop?
I feel it's worse TBH. I've tried several different roms and revisions and it still seems to be worse. Maybe I'm just playing with my phone more but my SOT can't seem to break 4 hours and it usually can't go all day on a charge.
Same. My battery life definitely seems worse.
I had better battery life on the developer Preview!!
this sucks
after removing Google Now and Google Fit, it has improved a bit, but still bad.
On some days it's pretty bad and on other days it isn't with pretty much the same setup... LOL
I accept the fact that battery has gotten worse with Lollipop, but I'm sure they'll fix this on the next release.
Chill~
Worse.
Developer Preview was significantly better than stick KK, final release the same as KK if not slightly worse. Was definitely expecting more from LP.
Sent from my Nexus 5 using XDA Premium HD app
mine is definitely way way way better
I'm a heavy user and its better than KK
I had the dev preview and Battery life was better than KK
Now on final release battery life is 1% drain per minute if I dont use the phone (but I discovered exchange services and gmail had updated from the one from the apk's I installed on the dev preview
re built again last night and max is 4 hours again without using the phone
2nd rebuld I did not restore anything
KK could be a day or 2 with using the phone before needing a charge

Ok, here is my xperia z3 compact not been charged for at least a day, has all the same apps and is used about the same as the Nexus 5 (z3 running kitkat, with NO power saving features enabled) and actually has a lot more apps running than Lollipop
and this is the Nexus 5 with only the apps you can see listed as running apps that was from a full charge overnight
It has dropped another 4% since taking that pic
In my case, the standby time of my N5 (which is new, I got it back from a RMA a month ago, so its battery isn't worn) is much worse on Lollipop than Kitkat: it drops 5% battery in one night in airplane mode, while 4.4.4 barely dropped 1%. On the other hand, the battery life when using the phone is way better! Before updating, I always got less than 4h SoT; now I get past 4.30 without even activating the battery saver.
So I'm not voting at the moment.
Mine is better than KitKat, some random drain's, quick soft reset fixes it.
Battery has definitely taken a hit wid L. Clean flash where
Mine's definitely better. I'm not a heavy user, but on KK I would need to charge during the day at work (usually afternoon time)...but now I can leave it till I get home.
I don't charge my N5 overnight, instead I wait to come in to work where I have a Qi charger on my desk. Usually I see it sitting at about 95% when I put it on the charger at work after leaving it alone all night. This morning I see it at 65%. I have never had it drop that low in one night before android 5 showed up.
What is even more interesting is that the battery stats claim that basically no one has been using any battery power. The highest number is 3% for wifi with 2% and 1% for a few other things, so where the heck did the 35% of the battery charge go?
I was in a similar situation as most people in this thread but currently I'm on my first discharge cycle on optipop rom with uber kernel and im on 4 hour screen on time with 20% to go.
I have google now off and location on and spent most of my time on wifi with avg cell signal.
I flashed the OTA manually and haven't done a factory reset, but the battery life is better than ever. 3 days and 9 hours, and 3.27 h screen on time. Brightness is set to auto.

Of course, if pay more games, I'll get it down much much faster.
I have some random battery drain issues too. But I think the issues belongs to 3rd party apps. In the safe mode there's not any battery drain. The 3rd party apps aren't compatible with Lollipop yet. So the main issue is this apps. Now 'Im trying to uninstall and reinstall the apps to find which apps drain the battery in deep sleep. I think which apps has a "cancel deep sleep mode" permission may drain battery if it's not updated for Lollipop. It's just a guess though.
First my battery life was really bad. I couldn't figure it out. I decided to do full wipe and it helped a lot. Now the battery life is better than on kitkat.

I'm getting worse battery life than any ROM stock or not I've run on the phone. I had better battery life on the dev previews. I don't think I've broken 3 hours screen on time or mixed usage(screen time+music time)once since the official image came out. I've done 2 or 3 clean flashes of the image and had also tried the Nexus 5 Experience ROM. I've used it each time rooted. Last night I did another clean flash of the image locked the bootloader and am going to try running it unrooted for a day or so with only 4 or 5 user apps installed. It shouldn't make a difference but I'm going to see what happens.

Sudden battery life drop, much less SOT with the same usage as before

So, on top of MIUI 11 completely destroying the battery life, I had another drop in longevity of a charge.
Could it be possible that my battery died after less than 6 months of owning the phone?
I'm not going to use AccuBattery as it's wildly inaccurate on every phone I used it on.
Get a battery stats app which can log the runtime & battery consumption accurately then try to post here so people can check it out... Something like battery battery stats etc
