worst android battery I've faced

I unplugged the phone that was fully charged then made two calls, 5 minutes each and I surfed the web for 10 minutes battery immediately dropped to 87%. Location services was turned off, brightness set to auto and I was connected to WiFi the entire time. The phone had never lasted an entire day I always have to charge it in the middle of the day to last. I know I only paid $350 but this is unacceptable combined with the camera auto focus problem. This is my 4th Android phone and the other 3 were so much better battery wise.

I'm on stock unrooted for the time being

Update: been using it for 3 hours about 6 calls medium web surfing dropped from 100% to 56%. This is too much :(
[Nexus 4 General] razball:
I would root and use matrix I use mine a lot calls for business some browsing etc and I get 4 hours screen time and it lasts till about 11 pm for a total of like 15 hours or so

So many variables it's like comparing apples with oranges. The only semi-worthwhile comparison is a single user's experience with this vs another phone, but even that assumes they've not changed their usage model, where they travel most of the time, and their operator. Really, you need two phones side by side and using them the same way, or it's all subjective... :(
[Nexus 4 General] Phatsnake:
Thanks I'll look into it. Is it a Rom, an app that requires root or something else entirely?

I have to say I'm remarkably impressed by my first day of use with the N4, off charge at 7am, returning to charge at about 11pm. I gave it a real good hammering (wifi hotspot, GPS, some light gaming) and by the time I came to recharge I had about 22% left.

Very chuffed
[Nexus 4 General] Vanhoud:
What about it? 4 hr screen on time is not bad
[Nexus 4 General] juicyjones:
After my first full day with the phone I'm totally pleasantly surprised by the battery life. I rooted and installed the Franco kernel on stock before I did anything, but I didn't change any settings or under clock at all except I switch from 10% brightness to auto sometimes if I need more brightness. I listen to audio books for several hours a day as well and surf the web at every possible break at work.
[Nexus 4 General] MIOB91:
Not as impressive as others but at least I feel the difference to my ex evo3d. Unplugged around 7 am and still going.

It does it for me :). I'd say it was medium use. A lot of texting, Web browsing, a few calls and some videos.
[Nexus 4 General] smanthrav:
This is from my first time charging this to 100%. Running Franco kernel with max CPU frequency of 1026 and undervolted by 25 MV. GPS and NFC off and everything else turned on with display at autobrightness.

I don't have a microsim yet so the usage is entirely on WiFi. I managed to get 15 hrs of standby time. Not bad but hopefully I'll be seeing 5 hrs like others on this forum

And coming from the Desire HD with its atrocious battery life(1230 mah battery) , I feel like I'm in heaven already

I was a bit disappointed with the battery life of my nexus 4 on stock, my benchmark being my iPhone 4. Since switching to a different kernel I've been getting better battery life, although some micro lag is apparent at times. I'll just live with that at the moment.

Now I can easily manage throughout the day, and get around 4hrs of screen time.

I see what everyone is talking about with the poor battery life. Turned off my wifi off for the whole day. 22 hours total on with 2 hours screen on. That's with no WiFi, Bluetooth on, a live wall paper that's power hungry on. Thinking I might trade in the nexus 4 for the Motorola x when it comes out. Way more battery, and much better camera. I think I pulled the trigger 6 months to early.
[Nexus 4 General] grafkanker:
I'm runnig rasbeanjelly and Trinity kernel too (latest versions). I don't have any wakelocks whatsoever. How am I not even getting half the screen time you got? GPS and NFC off, screen on lowest brightness all day.

You are correct, they never have had a good camera. The rumor is they are coming out with a Sony 13 meg camera (sony exmor sensor)on the moto x.
[Nexus 4 General] MrBelter:
Im delighted, after its first charge my Nexus 4 did 5 hours screen time. Some 3g use, plenty of wifi use, a good blast on Radiant Defence, some calls (very impressed by the call clarity i must say) and lots of texts, stock ROM but with Go Launcher on it.

on H+ for 8 hours and wifi for the rest . Lots of browsing, watched flash videos on the native browser, 30 minutes of voice calls, face booking, whatsapp, xda app and some sms. Touch control mod on the whole time, I am also using the ubuntu theme which uses the tsf launcher and a large number of widgets as posted in the attachments. Mpdecision was on, and the rom felt extremely snappy in addition to the supreme battery life. This was also on the first charge cycle.

Same thing I said lol.

But I'm rooted running stock rom debloated with Franco kernel r71.
[Nexus 4 General] :
Yesterday I also hit the 6 hours. At least with my (light) usage pattern. I spent most of the time browsing 9gag via the nine app, a bit of flipboard, whatsapp and XDA. I had 90% of the screen time on WiFi and about 75% of the whole cycle.

I use one of harsh's latest builds. I UV'd and clocked it at 1.35 GHz. My ROM is AOKP mr-1 build 2.
[Nexus 4 General] Crisisx1:
Nice. But my was mostly on data which consumes more battery. Didn't under clock or under volt.

I will try what I get on mobile data the next days.
[Nexus 4 General] mefistos:
I came from iPhone to nexus and I have to say I am impressed! I use minco ROM and Franco's kernel and my phone lasts for 2 days and I couldn't ask more:) I am really happy with my battery life :)
[Nexus 4 General] ran495:
After reading this forum for quite some time, i am still at a loss at how you guys can attain these times. i tried everything from franco, mark1x, trinity, motley (about to try harsh next) but i am still unable to get past around 2+ hours screen time and 12 hours on standby. I wouldnt consider myself a heavy user, aside from data on, some light surfing and around 30 min gaming daily. The only thing thats pushing to my phone is whatsapp. seriously, i am baffled. better battery stats just show most of the wakelock is going to mcm_hsic_host but what from what i read its been a recurring problem ever since. I hate to say this but i was getting better times on my gnex with james bond kernel. so if anyone can please provide me with a little insight on the matter i will be eternally grateful.
[Nexus 4 General] DowntownJeffBrown:
Dude that's really low. You might have a good RMA excuse there. That sounds like a faulty battery.

Yeah,or its a faulty battery or some app its not allowing your phone to deep sleep...
[Nexus 4 General] trillo69:
Install Cpu Spy and check if cpu can reach Deep Sleep status. You can also try "Flight mode" to see if there's something wrong with your battery before requesting RMA.
[Nexus 4 General] jarayn:
I'm with the guy you quoted. Only 1:45 screen on inside 12 hours on battery and it's down to the last 10% . That's with Franco r71 undervolted to try and get something even slightly acceptable out of it.

Not impressed with this phone at all. Nice build quality but everything else about it sucks ass.
[Nexus 4 General] Fille84:
Sv: The great battery impression thread

Get your phone replaced, then make a judgement dude. Your phone is a brick if you only get 1:45h screen on.

Skickat från min Nexus 4
[Nexus 4 General] starfarer:
I'm in same boat. The deep sleep IMO is not problem but the screen time is way low than what's everyone here getting with 2:30 hr the maximum. Thinking of RMA'ing but not sure whether that is a valid reason.
[Nexus 4 General] smanthrav:
Hmmm..I've only had this phone a week and havent had the time to judge its battery but it seems pretty good, especially on franco kernel. I'm at 87% battery with 3 hrs of standbytime and 50 mins screen time and a 5 minute VOIP call.
[Nexus 4 General] dokukinoko:
I noticed some wonky battery times when I was using a very cheap Micro USB Cable I just bought. It'd charge to 100% (and take a really long time compared to the included cable) and then within a few minutes off charging my battery dips down to 60-70%. I am not sure if it even really got to 100% in reality? Switched to a different cable and I get a good 4-5 hours of screen time with moderate/heavy usage, which I think is about par for a stock N4.
[Nexus 4 General] ran495:
yeah im not sure if its a faulty batt coz a friend of mine is also getting pretty much same times as me(a little better, hes on wifi). or is it a problem with stock rom? most of the good times i've seen are on non stock roms... although i wish this didnt have to be the case because i want to remain on stock as much as possible.
[Nexus 4 General] DowntownJeffBrown:
You can run the stock ROM (your current rom) with a custom kernel. If you want the stock feel with better battery I suggest Harshs kernel. He uses mpdecision and no kernel modding apps are needed. Just flash and be done kind of kernel. Id give it a try brother. On stock I would get 2.5 hours tops screen on time now I get 4.5 on a normal charge cycle. ID say the majority of that 2 hour screen time increase comes from running harshs kernel. Plus like I stated previously u can run stock android with a custom kernel.

You can give this a try....helped me. What hw version you have? (You can check in fast boot, power/volume down at the same time until info shows) If you have a hw version 10 you may benefit more than someone who has a 11.

How were you able to achieve these numbers with mobile data on? It looks like you didn't do anything with your phone except leave the screen on and use the xda app. Is it possible to get those numbers with more things going on? I'm on Franco Kernel r71 and my screen time is still 3 hours with data on all day. Same as stock kernel.
[Nexus 4 General] yfbc:
I think I'm going to have to take mine back as well. Just too bad because the phone seems great to use.

My battery drains 8% in an hour when locked, in general usage it just plows through it!
[Nexus 4 General] Capt.PP:
Those who planned on returning N4, would you keep using it if there is a battery case available?
[Nexus 4 General] Stretlow:
There's definately somehting wrong here, whilst the screen on and use time is not the greatest the idle drain shouldnt be like this (mine isn't and a lot of others isnt either)

Obvisously I dont knwo whether its a software (app) issue or hardware.
[Nexus 4 General] alpha beta gaga:
here are my stats since my last post 2+ hrs ago
[Nexus 4 General] aceo07:
Did you guys let the battery drain until the phone decided to shutdown by itself? And then charge it back up?

Based on some battery graphs posted, the last 1% might drag on 20 minutes (display on!). That means that battery isn't calibrated yet.
[Nexus 4 General] wizzywig27:
OK just tested it again and battery dropped 16% in 42 minutes!
[Nexus 4 General] juventuss:
I think you guys need to let it run down some more. On the first day I got the phone, I powered it on and let it run to pretty much down to 9. I charged it overnight and started playing with it heavily the next day. It breezed through the battery and I'd say I got no more than 5-7 hours of heavy usage (netflix, spotify, some maps) before it got down to 12.

Charged it again and for the same level of usage, I got about 10hours from heavy usage. It has gotten progressively better.
[Nexus 4 General] wizzywig27:
Just one more photo...

Yesterday I let it go to 1% then charged it, today it seems worse than yesterday!
[Nexus 4 General] alpha beta gaga:
my charging cycles looks like this since i got the unit on the 15th

? > 100% > 0% > 100% > 0% > 100%

each full charge done via a mains usb charger with nexus 4 switched off. the last 100% above is yesterday and i will just charge the unit as and when i need to now, only doing a full discharge/charge cycle every month or so
[Nexus 4 General] yfbc:
Exactly, I have also found that my phone will run hot in my pocket, anyone else?

Yes I have let it shut off by itself.

The idle drain is stupid, but the fact that the battery drains 1% every 5 minutes or so under general use is the most annoying thing, I can play on an iphone for 30 odd minutes-games, browsing and more with no drain at all
[Nexus 4 General] dale_cooper:
Agree with what others said - it takes about a week for a battery to properly calibrate, and for the system to calibrate (I notice this when installing new roms) - I had 28% left last night at 10:30pm, took it off the charger at 7am. Light usage and generally connected to wifi most of the day. but I'm never a power user. Not as good as my one s, but not bad, I'll wait a little longer to pass judgement.

Mine doesn't run hot when idle, if I'm playing games it will be a little warm.

I'll say this much, even if the battery is a little subpar - the device is way too nice looking and just sweet in general to return it. And this is coming from me who has a creaking nexus 4 with screen sensitivity issue (but I'm guessing everyone has the screen sensitivity thing). Every time I look down at the phone or turn it on and see pure google, i smile.
[Nexus 4 General] alpha beta gaga:
same here. haven't felt it get at all when using it. i don't play games so cant say on that score.
[Nexus 4 General] wizzywig27:
Thanks for that, see the problem I find myself in is I dont have a week, I have until Friday before my 7 day return period ends. So I either take it back for my SECOND replacement, keep it or return it.

I CANNOT have a battery that is on 44% at 2:30 in the afternoon. at this rate (which aint even high usage) it will be dead by 10pm! My S3 battery was on about 75% at this time of the day.

Battery life has been great for me. I just checked and I have lost only 3% in last 1:30 in standby. I have sync on and Skype running in background.

I have only charged it one time. When I received it yesterday, it had 90% battery, this lasted about 11hrs with 3hrs screen on time and I still had 23% battery left when I turned it off.
[Nexus 4 General] Stretlow:
What brightness was your screen on
[Nexus 4 General] poisike:
Auto brightness.
[Nexus 4 General] aceo07:
1:44hr on battery, 55 minutes display on, 7 minute call, 2 email accounts sync and emails in and out. Display at 1/3 brightness. (Auto sets it too dim here.)

Started at 100%. Now at 84%.

Not too bad since I won't continue at this usage rate for the rest of the day.
[Nexus 4 General] Stretlow:
Agree with this, whats the point of having an amazing screen if you practically shut it of to use.

I ran the brightness at 100% yesterday and got two hours screen on.

Running it at 50% today and im on track to get three hours.

As I pointed out yesterday after getting two hours, if I can get another hour screen on time out of it i'd be happy. The 50% screen isnt too bad for me (i love having the brightness upthough).

I have however disabled some stuff (location access, google now etc) im going to re-introduce these over the coming days to see if its any of those eating the juice up.
[Nexus 4 General] yfbc:
Possible I have a defective Nexus then? Mine is always running hot, even doing nothing in my pocket
[Nexus 4 General] FKNtrashbag:
I've only had the phone for about a week and I've already put the battery through about 12 cycles (yes, I'm abusing my new device). Out of the box, I immediately unlocked the boot loader and rooted the phone. I've been reading about the battery life since the phone launched back in November.

So I decided to test things out for myself and I kept both the stock ROM and kernel.

I don't have any screenshots, so you'll have to take my word on this... I have a rev-11 device.

After the first 4 cycles I started seriously watching my battery life. I was able to average only about 15 - 16 hours with 3.5 to 4.5 hours screen-on time, and about 12 hours standby time. This was done with manual management of closing apps, switching between WiFi and data ON/OFF, lowest brightness, default volume settings, and turning off touch/keypad sounds. I ran plenty of games (eg. Words with Friends, Scramble with Friends, and Temple Run 2), and did tons of web browsing.

After about 4 cycles running stock ROM and kernel, I switched to franco.Kernel-r53. I noticed the phone ran much cooler, and increased my average battery life to about 19 hours with 5 to 5.5 hours screen-on time, and again about 14 hours standby time. My usage of the phone has been the same with the same settings.

Lastly, after about 2 or 3 cycles on franco.Kernel-r53, I updated to the recently released r71. I've decided to UV by about 10% with all the same settings and same type of usage. I've only gone through 1 cycle, but my battery life has again increased to about 21 hours. I don't know what witchcraft he's done (because my phone is running warmer than r53), but my screen time has increased to 6 hours with about 15 hours standby time.

--- --- ---

tl;dr - rev-11 HW with stock 4.2.1 ROM, franco.Kernel-r71 UV'd by 10%. Getting about 6 hours screen-on time and 15 hours standby time with very heavy usage since this is my first week with the phone. Manual management of apps and WiFi/data.
[Nexus 4 General] ran495:
i have rev11. so im guessing this wont work for me. and im skeptical to just flash a stock image to improve battery. but i am hard pressed to get better battery life, so ill save this as a last option. in any case. gona try harsh's kernel now.

Me: "on the forums"

Them "lol .. no chance"

It also doesnt make alot of sense, you are saying that multiple people got a defective battery?

I prefer to think the people saying 3 hours screen on with 50% left are lying. Its tough being a sceptic but I find its more reliable.
