is this a good battery life?? - Xperia Z2 Q&A, Help & Troubleshooting

i want to know to if my xperia z2 battery is working as it should. I mean "is it a good battery life?

Not good, not bad. In my opinion "good battery life" means at least 5 hours 30 mins SOT

Oh alright, well then do you have any solution for it? As i am facing the same problem I have 5.1.1 and .232 and my battery has similar issues , It was only 3 hr SOT and battery is less than 10% thts because i didnt use any power saving options.

Battery life is an extremely wide topic. For example, I use greenify with exposed support, I uninstall unnecessary system apps, I control devices wakelocks regularly etc etc.. As I said so many things to do.

Your battery life is actually GOOD.. You don't need to worry about it unless the SoT decreases over time..

I agree, i heard that greenify can be effectively used once your device is rooted. So i see that u have rooted your device and hence you can able to uninstall system apps. I am in warranty period and i don't want to void my warranty . So any other solution would help ??

Freeze Google play services for 1 day.

This is insane!
i have this phone for a year and half now, yesterday i decided to freeze google play services and play store to see if i could have some gain in battery life... and god, i got plenty!
before i barely get to 5h SOT, now i can reach 7h with wifi always on, and screen on auto in house light or cloudy outside light , also the standby is outstanding too.
you guys should try it for 1 day.
Yes, there is the inconvenient of some apps not working, but give it a try!
ps: i am on all stock kitkat 20h. (no greenify or anything)
am using playservices lollipop debloated,servicely,and amplify. screen auto brightness... battery at around 30%still left i can still gain more with a few other tweaks.

Yes, my battery has deteriorated over the last 6 months. I'm on 20H also. :highfive:
My record is 103h with 2h SOT but now I'm lucky to get half of that with exactly the same usage. Even though nothing special is showing up in my battery stats, I'm sure its something OS related that has got worse. :crying:

That's not because of either amplify or servicely. With only 9h uptime and 6 hours screen, the standby drain has almost 0 impact. Also, you have almost no apps using battery (only browser and whatsapp). Couple that with periods of static screen(where gram technology comes into play) and that battery life is quite achievable.
Most guys on the g2 with 7h+ sot are usually guys who use whatsapp and apps like that, probably due to the static screen when waiting for new messages and etc and the low cpu use when idle.

I used player , freedcam,photoshop express,browser,whats app, telegrampower amp some apps dont show up..
but am pretty sure amplify works it stops wakelocks and alarms to trigger at a certain time..
we all know that . and you cant compare with games or apps they drain battery at different rates.. of course play a game adn you wont get alot depending on the graphics 3d games work harder on cpu.. well i tweaked amplify more and am pretty sure am getting more time..
here is an example for standby.
0% in 6h.
guys completly want at least 5 hours SOT, what should i flash currently on cloudy 2.2 but hear cm13 is good....
any tips with apps...

Agreed. My stock LP G2 can last at least 5 hrs at 100% on stand-by with no tweaks at all. If I don't use Google voice, I will terminate google service in no time.
Also agree with OP. Google service is a major battery drain but that's life with google. I disable google service on my kids phone "Galaxy I" and recharge cycle is about a week or more compares to a day. They can still get online and the chat apps we use still works.
Can't freeze my google app.. My custum rom not allowed this... Always boot loop...

[Battery life thread] Post your Screenshots !

Hi guys post your battery usage here in this thread to compare and see how this device battery endurance is :good:
Not much SOT 2 hours still but I base battery life off of background things since that's how I use my phone the most. Pandora for an hour took some pictures at the pool watched some YouTube videos light web/Facebook browsing. I love the battery life on this phone.
Theres already a battery life thread on the real life review section..

Too each is their own. Coming from the Galaxy S7 to the V20 now the G6, the G6 hands down has the better battery life
Took some photos, browsed web, played a game for around 30mins, if not more, at 50% brightness, otherwise i have it on auto brightness. I usually get around 5 or 6 hrs of SOT so i think the battery life is pretty damn great.
Sot is the worst measurement for battery. I wish people would stop thinking it's the end all be all.. A lot of people use their phones listening to music or having navigation going with the screen off. A lot of things can be used with the screen off that will drain your battery. If the damn phone lasts as long as you need it to while doing the things you do, thats all that matters.

True, true.
That's exactly why there's such a huge difference of SOT between me and StonerSteve420., who uses a lot of background tasks .

True, but sommetimes we can have 2 people with almost same usage but phone A doesnt last as much as phone B, it can help the user to check if he have a wakelock or app keeping his phone awake...you know what i mean
Bad standby, due to the continuous switching of networks but far better than G5 here.

S7 should have gotten you around 6 hours SOT, the G6 with careful management should give you 6 to 7.

That's fair enough a statement but most people who measure SOT still use background stuff.
On my S8+ I get 8 hours SOT over 2 days, using Deezer, Netflix, Calls, whatsapp, facebook, camera. The G6 gets me up to 7 SOT. So it's still a valid measurement.

Much lower SOT than month ago.

Hi! I own a RN4X for about 3 months. When i started using it I could easily get minimum 9h of SOT no matter what i was doing (usually im just watching youtube, listening to music and using browser). Now i can get barely 6h of SOT. No matter what ROM I am using or what kernel. Max 7h of sot. Are xiaomi's batteries so weak or just my device is kinda defective? Should i give it to warranty?
You are so spoiled.. there are barely any phones on the market that will give you 7hr SoT, also what you gonna say in warranty? That you have 2 hours less SoT? This guys in service center will face palm so hard..

That doesn't change thing that people i know still have 10h+ SOT on the same usage with that device after using it for a year. It just isn't normal that after 2 months my battery started to behave like its 2000mAh. And battery isn't my only problem. I've got a few bad pixels, headphones sometimes "unplugs" itself and phone starts to use speakers, awful signal in a big city (ofc only for me, i know many xiaomi users and their signal is pretty good in those areas)

There is no such thing as same usage between 2 people, 20% less screen brightness can give you 1 more hour sot if not more, different carrier = different signal = different battery life, there is thousands things like this which make battery life comparisons useless, dont be stupid.
Trust me, i've been using it on 40% of brightness and underclocked cpu to 1684Mhz. We all are using the same carrier. Our use is really comparable. I wouldn't post that if it was different.

try to do super clean flash... means you use OTG to flash... wipe all the partition on device, including the internal storage too....
My wife have been using mido since february and still got 10+ hours SoT, there is no performance or battery degradation. That makes me switch to mido too about a month ago... :laugh:
do not install use custom kernel, you see the long list of features but actually it's not necessary...
for example, Its absolutely not necessary to underclock the cpu... decreasing cpu clock will not increase battery backup.
When the cpu is slow, yes it will consume lower power on load... but It will need more time to load
When cpu is fast, yes it will consume higher power when on load, but it will go idle faster
calibrate battery usimg an app. you will any on play store. install any and calibrate. the must require root.

Of course i have twrp. I've been using custom roms. Yes, miflash an erase everything and then install stock images. I guess i will try it.
Well, i flashed stock rom via miflash. Still i can get max 7h of sot on LIGHT using. No custom kernels. No matter if im using a miui based rom or a custom. Still max 7 hours :/

Meh, I got used to it. If your phone is still under warranty they should replace your battery for free. Im too lazy for that.
same as me too , 10-12hr sot last two month when my rn4x still new , now only 6-7hr sot , using resurection remix with the same usage as before , and dead pixel keep increasing.

s9 plus exynos battery drain ( android system)

I have done factory reset atleast 5 times , but everytime 3-4 days later , the battery life tends to get poorer and poorer.
The day after factory reset - android system is consuming half the battery percentage of screen
But a few days later android system is taking alot of battery ( SCREENSHOT ATTACHED)
Can someone let me know that why is android system taking so much battery.
And what in android system ( like what apps ) are taking the battery.
Disable background activity for Android System.
Also, I get upto 10-12% consumption by Android system by the end of the battery without disabling background activity for it (10-12% turn out to be 50% of what screen consumes); though my SOT is consistently above 6Hrs.
Test the battery endurance in general and then judge if Android System power draw matters much.
interesting thread. For android system I also get 50% of what SOT consumes ... And I wonder what it can be and what are the consequences of denying background activity to it (activated the switch just now, I'll see if it changes something for me). I hope it does not disable notifications and so on ...
See the drain by Android system despite of disabling background activity.
It did not affect battery endurance; I'm getting am most same as what i was getting earlier.

You have 7 and a half hours of SOT and you complain? Your battery is not draining, you are using the phone, and the battery life is excellent.
Also more than 24 Hours of complete battery life on that SOT. This is incredible, I do not get any close to that. I am assuming that you are just trolling.

LOL, no, I'm absolutely not complaining.
I was telling OP that:
1. Things can improve slightly if he disables background activity for Android System
2. Android System consuming 50% as much power as Screen does not necessarily mean that it is the cause for bad battery endurance
I was giving example of good battery life despite of that 50% thing.

I don't have a problem.
My battery life (if you see the screenshot) is already excellent in my opinion with 2 SIM.
Shifting to single SIM didn't make any difference since network coverage is good almost always for me (I stay in a metropolitan).
I have already used the phone single SIM for a few days while it was new without any difference. Battery life was wise back then since phone was still adapting to the usage pattern though.

Poor battery life for me as well. Barely 15 hours with 3 hours SOT. With a custom ROM I got good battery life for a day or 2 and then back to square one.
I guess I will have to live with performance like many others.
Exynos btw.

Even i had poor battery. I did a factory reset. Reinstalled all apps separatley. Restored only contacts and sms. Formatted my old memory card. Now on wifi i get almost 7 hrs sot with more than 24 hrs battery. On 4G i get5.5 hrs sot with 18 to 20 hrs battery
You guys might want to try turning off "Find My Mobile" in Settings

limiting android system background usage had no effect.
Android system is an aggregate of a a lot of stuff so it could be ur wifi or an app. Install BBS to check.

BBS is BetterBatteryStats ... You can download from PlayStore/XDA
You can use the app to detect which apps are using how much of your battery percentage. However, you have to use adb to enable more stats inside the app. Using adb requires a PC
Guys I am also experiencing the same battery drain with android system. I mean it's the second in the list almost equal to screen. My SOT is 3 and half hours max. Tried factory reset and all. Restored apps manually too. Guess Samsung should release a patch for it. Mainly beaming services, Bixby, AnT+Hal keeps running in the background I guess.

Battery Drainage

after update of MIUI 9.6.18 is battery draining faster or I am only feeling this thing?
Yes, I feel the same. I'm barely getting just around 5 hours SOT on normal usage without gaming.
I don't think its true in my case, just today i drained it to 5% and sot was 7.5 hrs which included pubg 2 hrs, world of tanks 30mins, utube 1.5 hrs and other normal usage like twitter, little skype about 45 mins. sorry i don't hav the screenshot to show
I get 8hrs of sot.. I tried every thing to get drain faster but it doesn't drain..

Terrible battery life - 4-5hrs Screen on time
I am getting a terrible battery life with normal usage with just 4-5hrs screen on time. Also tried factory reset.
I notice andriod and andriod systems are taking most of the juice so i think its some internal software issue and not my usage or mu apps.
