4.2.2 and battery life

[yfan]

I just got a whopping 1.5hr screen on time on my last charge after updating! WTH?? Is something corrupted on my phone?

Just what were you doing with the screen on? If your phone was on navigation, for example, then GPS also drains your battery, and faster.

This is what weekends look like for me. No data, a couple calls, and a little bit of browsing. I usually do more with the phone, but I'm sure I wouldn't have gotten this much out of it before the update.

An almost impossible improvement for me. On standby, battery stays the same for hours.

the battery life on my N4 has improved 10 fold. I got 25 hrs of use (light use) and only 25% battery consumption.

let me be clear 24 hrs of use and I still has 75% battery available. since I have had my N4 I couldn't go 24 hrs and have even 50% avail doing nothing.

this update has made this battery issue non existent. if you want to improve your battery life do the update.

On 4.2.1 I'd get 8hrs of pretty heavy use.
With 4.2.2 I get 12hrs.

It's no Razr Maxx, but I'm still quite pleased.

+100000 totally true... my battery improved as well. my battery now drains nearly half when idle.. longer standby time and seem to have improved when on use as well.

I see exactly opposite, my battery life is atrocious on the GNex. In 4 hours 3 mins I am already at 60%. Screen is taking 41% of that and is on auto brightness. Usage, couple of short calls, mostly on 3G, some streaming music from play music, checking facebook, twitter couple of times. I have all networking options on, 3G, wifi, bluetooth, nfc etc. Wifi is on never sleep

How many hours of screen time are you guys getting? After the update I can barely get 2hrs!

Standby time is not an issue.

Standby time is not an issue.

I was getting around 2-2.5 before update. Now I'm getting 3-3.5 after update.

I believe my problem lies with mobile data. When I'm on Wifi I get acceptable battery drain but as soon as I get on mobile data my battery drops like a rock. I mean as bad as 15% in 5 minutes!

I didn't get official 4.2.2 update yet!!

I just noticed my battery life on Nexus 4 improved with this update. I'm a heavy user and so far today I've had my device on for 5hrs with almost 2 hours on screen time and I'm at 70%

My battery life is about the same, I haven't seen any noticeable difference.

Today after 3 hours and 47 minutes, I'm at 57%. I do have a lot of stuff running all the time: Tweetings push notifications, 3 Gmail accounts, 1 Active Sync account. I have Sensorly mapping from time to time (although this is a new addition in the past 2 weeks that did not change my battery life noticeably). I run Spotify during my commute to and from work, with A2DP, not many calls, but SMS are common (Chomp SMS turns screen on when new SMS arrives). I use MightyText often, so I'm not always reading or typing SMSs on the phone with the screen on. I also use Instagram often and Facebook from time to time, with some pictures here and there (and sharing them to Instagram and/or Twitter). I have accepted that battery life with my usage is never great. I had a 4S before and my battery life was about the same, so I think the Nexus 4 does a good job.

The only downside to the N4 is that it takes much longer to charge than the 4S did, but I still would take it any day over iOS.

This is the first day I used 4.2.2. My battery life would usually die at about 4:30 but today it lasted till 6:30. I start using my phone at about 8Am

Mine seems to have better battery life after the 4.2.2 update. I'm still trying to decide if it's a placebo effect. Numbers don't lie though; I now can get over 4 hours of screen time. Before the update I was doing good to get 3.

I'm hoping to see similar improvement. I just installed 4.2.2 today, will post numbers tomorrow night...

I just noticed my battery life dramatically increased with 4.2.2. 10.5 hrs off charger, freaking 40% left. And I have not been gentle with my N4 today: GPS and syncing turned on, much of the day spent on weak WiFi, lots of BT audio streaming.

4.2.2 is like a miracle update. i had 1.5 hrs screen time. 59 min on GPS(it drains a lot of battery) still got 2 days without a problem.

It improve the battery life significantly

Before 4.2.2, Android OS takes a lot of battery. After updating, Android OS only take a small part of battery.

It may be related with the bug of sleep on non-wifi condition.

Re: It improve the battery life significantly

4.2.2 has made a huge improvement for me. 70% remaining after 13 hours 45 minutes off the charger, Wifi and Data on, BT for a few minutes and no GPS and a little over 1 hour of screen time and a bunch of texts and a couple of calls. That is the same or better than my iPhone 4s was getting so I am very happy now.
