nexus one battery life - this is it for my nexus

ive had a nexus one since the day it came put and since upgrading to froyo and now 2.2.1 my battery lifes been horrible. my normal settings are no wifi or bluetooth on. no sync. im running uv kernels and my battery life is still horrible. i recently sent my nexus to htc thinking it was a hardware problem. the new nexus dies just as fast. ive almost literally looked at every battery life thread and tried tips and still doesnt help. my phone doesnt last 8 hours let alone 24 hours. ive checked my battery use and the only thing over 10 percent is my display which im using auto brightness. any help would be so greatful because ive tried everything i know how to do

Did you replace your battery?

Time to replace your battery!!!

already replaced the battery before i got the new phone.

Dude same here. It's obvious the N1 is lacking in battery technology. What new phones are you considering?

that's definitely a dead battery, I've got my Nexus One since 2nd March and keep using it till now, still there is 92% of usable capacity.

Check the battery cal thread. We just finally hacked the nexus battery EEPROM chip and can tweak voltage etc. The changes got merged this week. So maybe some hope still...

well these things can definitely kill the battery extremely quickly if you use them a lot.
i personally don't have a problem with the battery life on mine on a normal work day because i only use it probably on average 5-10 min an hour for a 9 hour work day and by then i'm usually at 50-65% battery depending on how much i used my phone.
if you suspect that the phone is the problem and not the battery then try downloading currentwidget its a small widget that will tell you exactly how much power your phone is using in miliamps. it takes about 1 min for it to refresh so it does not work in real time but this is kind of nice because it allows you to see how much power its taking (or receiving if its on the charger) when its in idle
mine usually reads 3-5 mA when i unlock it so that is what its taking when its in sleep mode.
the most i've ever seen it take when draining the battery is about 465mA i would say that the average drain when i'm using it for browsing websites and using simple apps with the screen at half brightness is about 350-400ma or so
one thing is for sure though if you use an N1 heavily it can and will kill the battery in a matter of hours, if i play angry birds for example with my screen on half brightness after a few hours i'm at about 20-30% battery easily and the phone itself is very warm from the constant CPU use.

and btw the bad battery life is the combination of the AMOLED that takes massive power compared to an LCD and the 1st gen Snapdragon CPU clocked at 1ghz, battery life without the screen on and with minimal CPU use like streaming music for example or playing music with BT headphones i can go all day easily. it only drains like 5% an hour maybe a tad more but the difference is that the CPU is not working very hard and the screen is off completely.

AMOLED using more than LCD? What did you smoke mate? ^^
AMOLEDs have been made for low power consumption, especially for black colors...no way it uses more battery than my SLCD variant...

they can take less power with the proper screens yes, they are dynamic in their power consumption like plasma's are in that how much power they use is directly related to what they are displaying and what the brightness (or contrast in the case of plasma's) is set at.
LCD's are predictable and constant with their power drain.
AMOLED's are capable of consuming more power than LCD's of the same size if given the right display material (mostly white, mostly brightly lit content)
considering that most of the websites and even some apps i use on my nexus have white backgrounds it explains why my screen pulls so much power when i'm using it

There was a test done somewhere that showed that all the phones with AMOLED variants did the worst in battery life. Best battery? Droid x

true, white on white, amoled does use more battery...but meh...argh it killed my point xD
haha yeah you're right I guess Websites should have black background and green text, just like my terminal, gmail, etc. meh ^^

that sounds jsut like my phone. 5 to 10 minutes of use an hour and im at 60 percent. that cant be normal! angry birds for 10 minutes is like 8 percent battery loss. like i said i got a new battery for my old nexus one then noticed that the "issue" still existed so i got a new nexus one and my phone still dies rapidly. why is it that some nexus ones are better. i hear people say they get excellent battery life and to me on a brand new nexus one with a uv kernel my battery life is still horrible?

It's normal there is nothing wrong with your nexus one they suck battery if you use them heavily

Battery Life

So I've been pretty unimpressed by battery life so far. Barely getting 3.5 hours
Anyone else getting better?

Gonna need more info than that. You talking screen on time? or total? under what settings? full screen brightness?

Yeah screen on time with auto screen brightness. Pretty much on LTE all day. Only disabled bloat apps.

Full day with it, unplugged at 3am and at 8:38pm cst, I am still at 48%. Now I don't use facebook or Tweeter so that helps my battery life. Wifi at work weak and slow so I am on LTE most of the time.

Same here. Only around 4 hrs with regular use. This device needs root.

Easily getting through a day with the phone. Most of the bloat disabled, moderate usage, Bluetooth/NFC/Wi-Fi always on, though mostly on LTE. I certainly don't expect this thing to last like my Note 4, but I'm pleased with the battery life. I get home with time to spare, and plug it in every night like any other phone, so its all good.

Root doesn't mean better battery life. My nexus 5 had about the same battery and got about the same battery life as my s6. And that's rooted, stock, slimrom, and cataclysm. My G3 has about 500 more mAh than the s6 and I get about 5 hours of screen time. Stock battery was better than cyanogen battery.
It's not 2012 anymore. Root is almost obsolete. It's good for app removal, rooted app functionality, and customization. Even if underclocked and undervolted it doesn't change dramatically. If u want a better battery, buy a phone with a bigger battery. MOST people don't look at their phone for 25% of their awake hours (if avg sleep is 8 hrs.) The s6 will give u 3.5-4hrs of screen time on 14-15 hours of use. That is plenty for MOST users

We badly need root. Rooting my phone has always improved the battery life and performance of your phone.

Battery life today was better I think. Screen-on time didn't even show up in the battery usage list, so i'm not sure how much it used. 20.5hrs since unplugging with 14% left.
This will definitely be a phone I'll have to get rid of after a year. With constant charging and a sealed battery, this device really doesn't have a long life. That's my main concern.

Someone in another thread turned off Enhanced LTE (Voice over LTE) under network settings and saw a much better battery life (or lack of drain).

I am experiencing insane WiFi battery drain. I am foregoing the use of WiFi in the mean time. Seems to help.

Same. I tested mine and the drain is far less with WiFi off all together. No WiFi and I can get 6-7+ sot.

I updated the Samsung push service and it seems to have improved battery life for me. I will also try turning off the HD Voice and see how it performs..

I updated mine plus turned off Wi-Fi and the hotspots setting in advanced Wi-Fi and battery life has improved. I still see screen as being one of the lowest factors for battery consumption. Our gs6 must have a very battery efficient display. Android os is now my top battery drain. I'm hoping an update to android 5.1 improves the system battery usage. I know it did on my nexus 6.

if you heavily use it well.. thats pretty normal.. mine can last a day if i don't use it for browsing just sms.. but for calling it would mean smaller life

I was getting horrible battery life like you because of cell standby but I disabled enhanced lte and did a cache delete in recovery and now I'm getting almost 5.5 hours of screen on time with brightness set at 25%-50% on WiFi/lte. If you want I have screenshot.

I can vouch for this myself. I was getting pretty bad drain to the point where I was about to return the phone.
The cache wipe seemed to work wonders. Along with deleting and reinstalling google play services (I searched google play services in chrome, clicked the link and jninstalled reinstalled uodates , then did cache wipe)

S6 Battery Life - TERRIBLE!

I've been using the TMO S6 for a couple weeks and my battery life is terrible.
I have used greenery to hibernate everything I can, but as you can see in the attached picture the Android system is running overtime. I am lucky if I get 4 hrs of battery time. I also have the screen brightness set to less than 50%.
Any suggestions would be greatly appreciated!

Note 9 drain over night

Hi all,
I having issue with my note 9, and I’m new to using note, is a 4% drain normal? Unplug at 12am and not use since and this morning I check battery was at 96% at 6.45am

How long have you had it. It takes some time for it to do battery optimizations but that drain doesn't seem too bad.

tat is only my 2nd or 3rd charge, have it only for 2 or 3 day

I have been draining about .7% an hour since I got it. I wish it was little bit better but the SOT more than makes up for it.

Sorry, but what is SOT? Screen on time?
So now on android ppl use SOT to measure if a battery usage is normal?

i usually get 1/2% overnight but when i had outlook installed i was loosing about 20% could be a app but 4 percent isnt something i would be concerned with... do you have AOD enabled?

AOD = OFF
Screen resolution = set to HD, (not FHD/UHD)

I have the same issue
I have snapdragon n9600ss first I have enabled AOD and sleep like 2 am and wakeup 8 am check and 90%
I disable AOD and now have 94%
It's the same percentage I have with my old s9 but with AOD so I don't really happy with battery
I will wait 2 weeks and see if get better

Wow I'm telling you some of you people have some really unrealistic expectations. Your complaining your phone looses a few percent in 6-8 hours. What do you expect? If you don't want your battery to drain then turn off your phone or plug it in. And then don't come complain you miss calls or have to have it plugged in all the time becusse your worried about a few percent while you sleep.

YoshiYino said:

Preferable to not leave it plugged in at night if you want to lessen the longevity of your battery.
~.7% an hour is not bad. With root and older phones I was able to lessen to 2-3% per 7-8h. Ideally that is what you want, less than .5% an hour. But we don't have root. Other ways to get less drain at night during sleep is to turn off sync or airplane mode or better yet turn your phone off. But as I said .7% an hour is all day for me in standby. I don't even know what it is at night, probably less.
I've been getting well over 10h SOT and had another hour or two of SOT left should I have chosen to drain down to <5% battery. I have been able to get 8h+ SOT over 36h on a charge. Your expectations are unrealistic as are many others on here. Be realistic or get another phone.

That's interesting has to be a app causing the drain what third party apps do you have installed? the screen res wouldn't affect anything in terms of battery life because the screen is off. I charged last night and I'm at 16 percent right now on WQHD almost been 22hrs since I charged my phone

10hrs of SOT? That's crazy I think 6 was the most but this battery definitely gets the job done for me

Change the resolution to WQHD+, the power saving is too little to worth the downgrade of screen quality. Tested on s7e,s8+ and s9+ and read about it for note 9.
Also worth to note that iphones tend to show less drain at high percentages and then speed up after below 60%, i.e. if you leave the iphone over night with 30% battery, most likely it will drop 1-2%. Still, iphones standby is a little bit better vs android and samsungs. I achieved 1% drop over night or non in M8 android 4.4 times, not since them. My best is around 0.3%/h via root and custom tweaking, for samsung stock it's normal to have 0.4-1%/h. Hope that brings some clarity.

How do i see what apps is draining the battery?

Natural Tone.

Should this mode be on or off, what are the pro's and cons of this mode and does it impact battery life or performance?

Maybe it has 1% of impact on battery life cause I've turned it ON since my phone has arrived and battery life never fails to impress (always 6+ hours of screen). This feature just regulate screen temperature matching the light around you in order to stress your eye less, so yeah it's good to leave it On.

The bad thing is that the colors won't be very real.
