My personal experience with the NS4G's battery life is that it's way better than the EVO it replaced. Only thing is, like others have stated, charging seems to be horrendously slow with the Motorola I've been using even with the EVO.
- Motorola charger (850mA unit): I'd estimate that my battery goes up maybe 20% in an hour. Using this same charger on my EVO used to charge it from empty to full in about 1.5 hours.
- stock EVO charger (1000mA): This charger is next to my bed to charge overnight so I don't know how slow/quickly it charges the NS4G.
- stock NS4G charger (? ma): Still in the box.
Compared to my Palm Pre- my battery life has been great. It does take a while for it to charge but I use WIFI, text, check email alot, play a couple of games and had some pretty long conversations on my cell and have never gone below 20% for the entire day. I don't get 4G in Phoenix AZ:'(
mine is less than desired -- perhaps someone can give me some advice.
I charged overnight - 95% at 6am (tho i know 95 is normal)
in 19 minutes it dropped to 88% - here's what was going on:
rebooted to clear out apps running
the following are running-
settings - does this always run?
switchpro widget
adv clock widget
weather channel
juicedefender
smooth calendar
com.adroid.sprintmenu - i have no idea what this is- under services it says 'HiddenPhoneService"
Market - an alarm app scheduled
google services
music- went to music app and a song is paused- i see no 'stop' function!
maps
noled
android keyboard
screen brightness is set to auto and is presently at 0
screen timeout is 30 seconds
wifi is on - i'm in my home with wifi - plus i have an airave in house - 3g and 4g are not on
bluetooth is off
launched dolphin browser then read one article. checked directv listing. checked two email accounts. installed one app update. that's it - and it dropped to 88% in 19 minutes
yesterday i was out of the house (no 4g, used 3g only) BT off. Had minimal use (one call, read about 5 emails, some browsing - about-5 minutes worth, did a quick WHERE search) and dropped 44% in 4 hours.
i know i shouldn't force an app to close - but something doesn't' seem right. just in the 10 minutes i'm typing this (i'm slow) it dropped 4% and i wasn't even using it! wifi bars are full as i'm 2' from router!
I have my brightness turned up about halfway because I find automatic brightness to be too dark. Anyways in the battery usage area it says display is 65-70% usually. I get about 12-16 hours of battery life a day depleting from 95%.
I was at 65% after about 19 hours of regular use- email, 50 minutes streaming on wifi, 3-4 calls, many texts, microbe live wallpaper, GPS on, etc. This is on my rooted stock ROM with the Netarchy kernel and nothing else
wow - i'm impressed - can i trouble you guys to let me know what's running on your nexus after a reboot - i have listed mine above - i'm not getting near those hours. also, if you can include your settings on screen brightness/ timeout, email and sync would be very helpful.
thanks kalex - that helps- my displays at 56% - set to auto - i just changed it to zero. does that number take a bit to reset? also - does display include whatever juice widgets consume?
My display is on auto brightness. but just to state it again this is with very low usage. few phone calls, texts a bit of browsing. definitely not heavy usage
Display is only tracking display power usage thats it. I don't think it tracks anything else under display
