Poor battery life? - Xperia Z2 Q&A, Help & Troubleshooting

Is 3 hours of screen on time on Lollipop good? I keep hearing of people that get 5 or 6 hours of screen on time and No android device I get has ever achieved that. Even my xperia z3 tablet compact can't get over 3 hours of Screen on time. Am I doing something wrong? Like could I be using my device too much?

check apps wich draw most battery and get rid of them , if this won't work then do a factory reset ...

I get between 4 1/2 and 7+ SOT hours.
Depends mostly if I turn Bluetooth on (SmartWatch), GPS use (Google+ position tracking, weather),use a lot of Internet (chrome is a battery sucker, you don't believe it), sync a lot of mails n stuff like that.
Of course it depends on your apps, but 3 hours is really not a lot, may be your battery is not good.

The 3 hours screen on time is with heavy usage but the standby time is amazing.

I get 3-4 hours screen on time too. However, that's with heavy use. Viber, Skype & Talkray for 1-2 hours per day. I get 2-3 days standby with 3-4 hours screen on time based on the above. Also some light web browsing and some WhatsApp...

It very much depends on a rom.
I was able to get around 4-5h sot on lollipop, but it was on Google style rom. On some more customized or stock roms you may get a bit worse battery life.
So to answer your question, 3h is a bit below the average result.
The reason may be an old battery.

Old battery? My Z2 is only 2 months old and was bought brand new. :laugh:
Perhaps rom related. Most ever SOT I got was around 4.5 hours and that was on Lollipop Google style rom...

amaze vs galaxy battery life

i have a galaxy and im getting some ridiculously good battery with custom rom, im at 10 hours with over 50% battery with moderate usage, i was thinking about switching to amaze because i really need led notification and camera button, can you guys let me know what the battery on the amaze is like how much usage and what percent u have ? i know itll be worse then the galaxy i just want to see how it will be to help me decide
I'm still figuring out exact battery life times, but I'm getting about 5-6 hours with very heavy usage (screen on for about 2 hours total according to battery use).
I'm at 9 hours with 12% left. I'm running unrooted totally stock but with Juice Defender Free on aggressive. Fairly heavy usage since I just got it yesterday and am constantly playing with it. That usage includes 60 min with My Tracks (gps) and PowerAMP running while out waking the dog. However I did have it connected to my pc for about half an hour while i was transferring music.
amaze
damn thats not looking good, anyone that rooted and installed one of the roms get better battery ? because 9 hours with a battery app doesnt sound too good, im at almost 15 hours with my galaxy and i have close to 50% battery left, with moderate usage (some facebooking, lots of text, emails,15-30 mins of gaming) not going to lie the battery on the galaxy with the rom i have is kind of ridiculous, best ive seen, but if the amaze can at least hold for 16 hours on moderate use on a full charge or 12 hours on heavy id be happy

ok
ok thanks, how many hours do you think youd get with music, several facebook notifications, lots of text, several emails and maybe 10-15 minutes of gaming and regular widgets ?

How long does your battery last on your SGS2?

Usually, on weekends, or holidays, I use my phone for Angry Birds, many other games, music, etc for a long period of time. Today I managed to get about 5 hours use until the battery got to 30%.
I'm not sure whether or not this is good or bad and so I'm wondering; how many hours do you get out of it, in relation to being a heavy user, medium user or light user?
Thanks
about 5/6 hours max
With normal usage 24-30 hrs. Wth heavy use, 8-10 hrs.

pretty much the same
always have 3g on and im quite sure i listen to music for 7 hours at least while im at my office...and by the end of the day i have like 20%
10 days and still going
With all data disabled most of the time, almost unused, but still connected to the GSM network, mine is now at more than 10 days (and I think it wasn't even fully charged at the start of this period). This is with stock ROM, Apex launcher, almost no other custom apps.
It's hard to have an effeicient answer since it depends on many factors : the way you use your phone, your ROM , Kernel and all setting stuffs etc ... . And even with same settings , two SGS II can have a totaly different battery drain. So, you can compare but it wont realy be so efficient .
Anyway , for me with a usual use : almost 2d and with heavy use about 16-24 h. I m on Wanamlite 10.6 with last Siyah V3.0 Kernel.
At weekends 5 hours max weekdaus prob 8-9 hours
Mod or Die
Plenty of hourly syncing and light use....
Stock rooted KL1 + LPR radio
I have tried 3 different ROMs and with the last ICS ROM i had 8-9 hours with heavy use of 3G/Bluetooth/sync ... and of course it's depends of what apps (games ) i use among the day ...
awesome how some users get 24 hours with a single battery charge.
When I use my S2 as a normal phone, about 20 hours.
But with heaving usage and gaming (which I do pretty much) probably between 6 or 8 hours also.

Woah :O Doesnt matter had "10days" :O
i guess screen on time is more important than overall battery time. I Used to get 4hr screen on time with a full day usage which is quite good for me and i think its average.

+1 Agreed here are some on my screen shots.
Usually prefer to watch youtube video's through browser So flash is must & it is a nice battery drainer too.Plus 4 hours of non-music playback !
Brightness - 20%
When i use gprs heavily it is very less!
Normal use may last a day!
Playing games also burns the battery pretty fast!
I have a Superatmos ROM installed in my Galaxy SII i9100G and I get around 30 to 35 hours of standby time with normal to low use. I do however browse the internet over WiFi some 4 hours a day.
I am quite happy with the performance of my phone.
So far its three months but its like Triggers Broom .

How do people get around 2 days of battery Life?

I'm actually quite baffled. Max I've had is around 20 hours with 4 hours of on screen time. People get around 2 days with 5 hours of battery life. How is that possible?

If you cannot cope with average one day battery life buy a dumb phone .
Often these users with long battery life do not put up the true facts .
Two days since i last charged and 76% left .
But i have not had everything running all that time .

Screen on time is a slightly better indicator, but even that varies quite a bit; reading an ebook = 9hrs, playing games/browsing = 4hrs. Leaving on the shelf in airplane mode = 8 days, but what use is that?
Best battery saver I've found is Greenify, kills all the useless and sloppy coding that eats your battery but the app still works when you need it.
I thought of the same. Just wanted to confirm. Thanks.
- Lowest brightness
- 2G Only
- Wifi, Gps off, all motion gestures and active view off
- lots of bloatware removed
- whatsapp auto dl photos off
I can get 3 days with stock battery and 2 days of hard use.
lol I could get 3 days without touching the phone.
I do believe that 4hrs screen time is pretty decent.
hell I can even get to 3hrs....so I have a spare battery with me 24/7

Screen On Time/Battery Life - Faulty Phone?

Hi Everyone,
I'm just wondering if I have an issue or not. I've already went through one G5 which was severely overheating and was giving me less than 2 hours of screen on time within the first week. I'm on my second G5 now and have had it a little over a week, but the screen on time seems to be dropping drastically. When I first got it, I have a SOT of 5+ hours. Then it got progressively worse until yesterday it barely made it to 3 hours and today it was under 3 hours. I'm a fairly heavy user, but it seems like I can literally watch the battery percentage tick by when I have the screen on. In fact, it seems like it's markedly worse when the battery is under 50%. For example, today at 50% I had a SOT of about 2 hours 15 minutes, and then for the last 50% it was like 45 minutes TOPS before it was drained. My standby time is absolutely amazing, with it losing less that 1% in five hours.
I just don't know what to do. I have 5 more days before I can exchange it no questions asked. I just see some people with 7+ hours SOT and it seems like mine is heading in the opposite direction.
Cheers,
Bloody
3-4hrs of SOT is average/normal
3 hours of SOT is on par, or very slightly subpar, with other users. Some, like me, get a bit more, but just because i do not use Facebook, or games. You should consider which apps you are using, if there's something always on and in "Sync" it's gonna eat up the battery a bit more. If you game a lot, same. That said, this is not a huge battery, but it should be big enough to get to bed. Can i suggest maybe (i know its obvious...but!) cleaning up the recent apps, taking more care in switching on and off the wifi...this kind of things could get you 30+min more in a day which could be enough to get trough the night.
To answer your question, you probably have not a defective unit. If this SOT time is not even close to what you need, the brightness of the screen poses a big problem for you, and you don't care as much for the awesome camera compartment, or the swappable battery, and you dont hate touchwiz, and you can return it no question asked, the s7edge has better battery time, and higher brightness and saturation.
I average 3 hr SOT. It's normal. Total 13.75 hours on average with 5.5 hrs active.
With the brightness about 30%, I could have about 4 to 5 hours browsing web with wifi...

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Google Pixel 3a before depleting the battery.
Then, drop a comment if you have anything to add!
Stock Android 10
Everything on, WiFi, BT, location, screen Auto brightness, dark Mode.
Im coming from the op3 a 4h SOT device so im quite happy with the battery life of the p3a

You got 8 hours on the regular one? I used to have the 3A XL but then gifted it to someone and an now using an galaxy S9. Really miss having a pixel though so am thinking about picking up the regular 3A and was wondering how the battery would differ

Yes it's the 3a. I think i could get more SOT without gaming.
From full charge to zero, I could get about 10hrs of screentime consecutively browsing, but that's not how I use my phone. In 48hrs of 'normal usage' I get about 5hrs of screentime.
I do about 3-6 hours of BT audio streaming daily which is why there is a larger than normal screen off usage. Still nice average SOT. I have so many sessions because I try to keep my battery between 50 and 80% for longevity.
I get 8 good hours.
What does Android 10 Battery say? Screen usage since full charge? Also Full charge lasts about???
Mine says 1 day 11 hours of typical usage. I always charge at night so it has rarely if ever run out.

Well I switched back to the 3a (regular version this time not the XL) and I'm getting about 4 hours SOT. Brand new.

Worse, on the best day you can get 6.5-7 hours on the regular. On the XL it's possible to get 9-10
I got my pixel 3a a couple weeks ago and struggling the last week or so getting more than 3.5 or 4 hrs SOT. I did use GPS for a 2 hour drive home today but it's 3p and I'm down to 10%. Idunno what's going on.
Here is the other day :/

the app usage of 66% is a clue. maybe you got some crazy app eating up battery. if you have bluetooth and/or wifi scanning on continuously that can drain a bit. gsam can be setup to show which app is using most by doing the adb command. just select apps for the details if you have not already.

Check out the second screenshot in that link. I've setup this via adb and had that included originally but probably wasn't obvious

Here we are after factory reset and flashing the latest OTA from
https://developers.google.com/android/images
Still can't hit 4 hrs SOT. Not once. I really don't know what to do at this point. Incredibly frustrating with everyone else on this thread having MUCH better results.
GSAM is showing some pretty beefy wakelocks on that "RemoteSoundTriggerDetection" and "*alarm*", ActivityManager-Sleep, etc.
I bought it from Best Buy. Should I go up there and see if they'll replace (highly doubt it) ? Maybe flash a custom kernel?
screen on time is a function of what a person normally does with a phone. one way to get high screen on time is you could set display intensity to 25% and timeout to 30 min. if you need that number to be higher. just let the screen be on as much as possible. when you first got it did you fully charge it then fully discharge it then fully charge again? screen on time is about the last metric i ever think about. i don't understand at all why it's so important. i'd be willing to bet some users set intensity to 20% and time out to 30 min or always on and do very little else then they get s.o.t. of 8-9 hrs or higher and think it's great when it's a joke. that's the way i look at it anyway.

Not sure if you're replying to me but I'll answer anyway. Yes I fully charged it then fully discharged it then fully charged again when I first got it.
It's not the SOT that is so worrisome but the constant Android system and kernel drain on my device.
I'm getting worse battery life on my 6 week old 3a than my 2.5 yo OnePlus 5 which wasn't good to begin with. This device was lauded for having excellent battery life and I'm not seeing it.

It isn't that at all. I found using it for anything where the phone needs to utilize the GPU a lot, like gaming, drains battery substantially. "Light" workloads, like web browsing, using social media apps, streaming video, etc give you really good battery life. Once I start up a game, I see about 5-6 hrs compared to 9.5 hrs if I just stream YouTube, check the XDA app, email, Reddit, etc.
