I'm switching to the nexus s in a few days

Is the battery life good?
How is the 3g? Does it go in and out or stay connected

Both depend on you usage habits and region.
I can go a day on a single charge and have no data issues
Sent from my Nexus S

with:
netarchys kernel
voodoo colors adjustments
running at 1.0ghz
automatic brightness
GPS on
syncing on
average usage of maybe 2-3 hours of browsing and data i get roughly 60-68% at the end of the day at 11pm.
never have any data issues of it dropping.

[Q] is there a way to keep data connection on without it killing the battery fast

is there a way to keep data connection on without it killing the battery fast

I have data on all day and battery lasts a whole day, it's usually on about 40% when i go bed

Yeah, I've never turned off data.
Maybe with HEAVY game usage it might be worth it but for everyday use I like to stay connected.
I have ebuddy & Skype running and loads of **** set to sync every hour or half our and the battery lasts easy a day at work & most of the evening.
It's only when I'm smashing some heavy screen on time (4hrs+) that I'm needing a recharge.

If you are on a 4.0 based firmware, then if you turn the automatic network search off and manually set it to your network provider, that usually helps a lot.

turn down your screen brightness.. if you bought the auto brightness app from the market it will definitely help... my battery lasts about 10-18 hours depending on the amount of games I get into in one day..

Poor Battery Performance of my S 2

Hello everyone,
My S2 only last for 10-13 hours and it drains battery too fast. Tried everything and nothing happened.
In my phone i disabled almost everything which drain battery.
No Facebook
No auto syn of Gmail
Access location is off.
GPS Off
Soft key light/Vibration off
No skype
Disabled Accu weather app
Disabled many others bloat ware
Brightness is set at almost zero level
Better Battery Stats show connectivity wake lock. i think ghis the main problem for drain.
And plz tell me how can i set my phone to only gsm. There is no option for that in phone. In setting it says GSM / wcdma and only wcdma. I set it at gsm/wcdma. Am from Pakistan and here there is no 3g/wcdma.
And if by dialing *#*#4636#*#* i choose gsm, it comes back to gsm/wcdma. Is it draining battery?

<nvm, didn't read properly...>

what ROM are you using ??

What!?
You wrote "My S2 only last for 10-13 hours and it drains battery too fast."
On attached screenshot you have 80% left after 6 hours of usages whereas 48% is used by Screen and 17% is used by Boat Browser.
You have to expect about 1~1½ % drain per hour ... even if you don't use your phone.
Screen drains a lot depending of your amount of Brightness! If you can get 4 hours Screen On, your happy.
From what I can see ... your battery time is totally normal!

I have Stock rom ICS 4.0.4
My cellphone is branded version and it comes from 3 Mobile UK.

no its not normal.. today i charged it and not use it for 2 hours.. i put it on airplane mode and leave it for 2 hours after 100% charge, to check the partial wakelocks.
I thought this time connectivity service wakelock doesn't appear but it does.
i thought connectivity service wakelock is due to mobile signal but when i put it on airplan mode for 2 hrs this partial wakelock still appear.

Hmm , I am not a Fan of ICS though, but the battery time which you have shared (Just Saw it) LOL , it is totally fine , and secondly , use a safe kernel to root the phone (PhilZ Kernel) link is in my signature , and then Flash NeatROM Lite v4.0 , my battery lasts easily 18-20h and i am a heavy user of the phone with Calls , Messaging , FB , Twitter, Whatsapp, Viber & Tapatalk
Follow my guide which i posted Here

PLS STOP with all this Juice Defender nonsense! A task killer often will drain your battery even more ... some processes will just restart again after you have killed it.
On newer Android version (GB and ICS) I haven't found any task killers that actually prolonged my battery time.
Adjust your screen brightness as low as possible, use a dark backgrounds and themes, get rid of unnecessary Widgets and Live Screen backgrounds, Sync Mail, Calendar, Twitter only when needed ... and then you will be fine :good:

My Razr M softbank never deep sleeps

As I am running a stock xt905 rom with xt902 radio on my xt902 and I have many times flashed a new rom and many times reset the fone via recovery
Betterbattery stats show kernal wakelock of suspend_backoff
I searched it and did the settings in chrome but still no help.
The processor keeps running at 384mhz as indicated by cpu spy even when the screen is off
And I have also tried stick Verizon xt907 rom and it still shows the same battery drain!

To my knowledge, the processor in these phones can only go as low as 384 MHz. With certain governors it will turn off one of the cores but that's about it. How much battery life do you get before a recharge?

Wow that's strange... I'm afraid I wouldn't know. Check your battery stats and see if the phone is awake while the screen is off. Also, try changing governors to something like msm-dvsc. That should put your phone into deep sleep properly.

Battery ?

I am on 4.4 with ak kernel. Default settings. 3g and Google now are on always. I m getting about 10 hours of battery with roughly two hours of screen on time. Is it good enough or can be better ?

It can be better. Download Trickster Mod and Unvervolt and reduce CPU frecuency. There are a lot of good threads with the optimal settings for that app.

Hmm. Can you point me to one please ?

No i am not in the PC but just Google trickster mod battery settings nexus 4.
Maybe u have some apps running in the background. Use greenify to freeze them and stop CPU wakelock

There are a lot of factors that can affect the longevity of the phone's daily battery life. Apps that are constantly running in the background will drain your juice. Lowering down the brightness will lower the power consumption greatly. Disabling location services should help. If you're in an area with bad service, your phone will use more power to stay connected to the nearest tower. Tweak you kernel settings or try a different kernel can help.

for a fairly default installation with i would say 10 hours with 2 hours of screen time is normal.
But there are some good advices in this thread to optimize it a little more
