Display uses most of my battery.

So I've acquired an HTC Sensation and have unlocked, rooted, and installed a few ROMs so far. Stock, CM7.1, and Android Revolution HD. That last one is the one I'm on.
My battery life sucks. Whereas my Blackberry Bold 9700 would go one to two days with constant, heavy usage, this phone gets about 4 to 6 hours. My battery graph says that Display is using 80% to 90% of my battery. I've turned off auto-adjust and set the brightness to minimum, it hasn't helped. Am I ****ed?
I've tried other things, underclocked to 1Ghz, different ROMs, battery calibration, no HTC Sense account, no friendstream, disabled background data and autosync. I've tried everything, and yet the display is totally destroying my battery. Keep in mind too, I mentioned the Blackberry, but I've had Android experience before. I'm not a total noob, and I'm not a pro.
EDIT: If you've got semi-****ty battery, check my last post on page 2. It might help ya out. http://forum.xda-developers.com/showpost.php?p=19062683&postcount=20

That's an LCD screen for you. It will always be the biggest power consumer of this phone. I believe that in general, the screen will always be the biggest power consumer of a phone, but LCD is especially bad. It doesn't help that the Sensation has an average-sized battery either.
That said, I can't believe your battery life is that bad, considering you've underclocked, tried different ROMs, calibrated the battery (although I've heard that this can actually decrease batt life), and disabled background data. Make sure you have matching radio + ril in case you haven't yet. I just can't believe that if you're doing all those battery saving tricks at the same time that your batt life would still be bad. Or did you try those things by themselves? You should try several things at once, but I'm assuming you already have.
LCD screen tech really needs to hit the grave. I like qHD resolution, but otherwise I hate the Sensation's screen. I don't get why so many Sensation owners think it's a good screen. LCD is absolutely worthless outside - I turn brightness all the way up and I can still hardly see it. I don't care if SAMOLED has oversaturated colors - as long as it's usable in any conditions I think it's better. Not only is SAMOLED much brighter and usable, it is much more power efficient than LCD. Honestly the screen alone of the Galaxy Nexus is making me consider it just because I hate the Sensation's screen that much (as well as other things about this phone).

I'm doing them all at once. I flashed the radio that mike (author of the ROM I'm using) suggested because he said the RIL file(s) are built in.
I'll post a battery stats screen cap when I can, but I don't have the means to do so right now.

Edit: There it is. Normally, I don't partial charge, but I had to take it off briefly a few minutes ago. As you can see, it was hitting critical levels around 5 hours in before I threw it back on the charger. The line drops steadily usually when the display is being used.
Here's the shot that claims Display is the culprit.

I feel like android never goes into detail as to how much being on 4G drains your batteries. If you switch to EDGE (2G) only, you could see an improvement in battery life. You can get to it from Settings>Wireless Networks>Mobile Data.
If that doesn't work out for you, consider trying out Juice Defender on the market, it's helped me extend my battery life a considerable amount. It does nothing while you're using your phone, but when your screen is off, it'll disable mobile data, and every 15 min (or 30, you could change this in settings), the phone will enable mobile data for a minute so Facebook/Twitter/Messenging Apps can sync.
Aside from that, you can try turning down the brightness levels.
If you're willing to shell out a little cash, your next option would be to cop an Anker battery from eBay or Amazon. This would help the most, imo.

I have tried many things but so far the biggest thing to affect my battery life is disabling bluetooth. That alone takes about 2% per hour of battery life even if I never use it. My usage is light with some games, mail, and texting. Included is a snapshot of today's random usage. I don't know why but my display isn't listed in the snapshot.
One thing I would check is the spare parts app that hopefully is included in android. Look at the battery history->other usage->since last unplugged. Specifically the percentage of running. Mines says running is 12%, screen on is 4%, wifi on is 83%. If your phone is 100% running, then it is never going to sleep.

Is the Sensation a 4G device? if so, which carrier?

Not real 4G, max speed 14.4 mbps where available for TMOUS.

Ur comparing the sensation to a bb 9700? 9700 is not dual core or a 4.3 inch screen. Androids typically have the worst battery life when compared to iPhones and blackberrys. Also HTC phones usually have the worst battery life out of all the android phones.
How long have u had ur phone? Have u gone through at least 5 charging cycles? Did u calibrate ur battery after flashing new roms?

The other day I got this...maybe it makes you feel better...(1900mAh Anker Battery)

@secano,
What game where you playing? I have played some that will kill my anker battery in 3.5 hours but never in just over 2!

I have the same problem, more or less.
I had a great improvement installing "juice defender", this app cutting off the 3g as soon as the screen is off, putting it on once every hour to chek mail etc.
try it.
it's an improvement, but my battery drain remain awful. I had a HTC HD2, and was used to 4-6 ma, now, if it's under 80, i'm happy...

Turn the brightness down. I only use auto brightness in the daylight. I used a app called dimmer to turn the brightness down to 10. The minimum setting the phone will allow is 30 so dimmer turns it down more. The dimmer app is nice it switches brightness down to 10 and the next click sets it back, so I have it switch between auto and 10. Full brightness will kill your battery fast.

I never directly compared them, I'm just sharing my past experiences. I never expected the sensation to come even close in battery life.
anyhow, ill try juice defender and my Bluetooth and brightness are off and set to low. it just sucks cause I seem to only lose a lot when the screen is on, but I don't want to blame S-LCD because this seems to only affect a small percentage of users.
worst case scenario, ill buy a new battery. thanks everyone for taking a look, please excuse the grammar, on my sensation right now

@OP... don't worry about battery life. I am in the same scene as you are...
Running an HD game would drain by battery in 2 to 3 hrs with lowest brightness and everything off.. My only problem is low network signal...
if you start using your mobile as laptop like playing games etc then you get as much time as a laptop gives u... But if you use it as a phone, out will do all say..
So either change device or line with it..

In Android Revolution the kernel spends the battery. You can flash the bricked kernel and you will see the battery life in normal use under 20 hours. You can find it under android development for sensation here in xda. I flashed yesterday and with wifi on and all sync on I have 45%. 12 hours from the last charge.

I will most definitely try this when I return from work. I may have to flash cyanogenmod, which seems to give me slightly better life. is the stock AR HD kernel really that bad?
edit: okay I went ahead and flashed the bricked kernel while at work. hope it helps, but I lost 10% battery to do it and I'm down to 20% left. we'll see how it does.

From what I read we have a new faux kernel. You can check it after bricked.

Hey guys. Small update.
I am recalibrating the battery, again, yet something special is happening this time. I ran the phone down and it played a 1080p video on max brightness with wifi, bluetooth, gps, background data all on. It played the video for 15 to 20 minutes while sitting at 0%! Now, I'm currently recharging it and best part, it's been at 100% and still charging, orange LED and all, for about 40 minutes now. Considering my charger charges at .75A an hour, thats something like .50ish A, or 500mAH that I didn't have before. That could explain my pathetic battery life. Imagine if it charges at 100% for an hour! That's 750 mAH that I lost due to bad calibration, half my battery!
Hopefully with a few more cycles, and some good luck, my battery meter will correct itself and I'll see regular battery life!
edit: Two hours In, I'm overclocked to 1.5ghz, have max brightness, wifi, GPS, Bluetooth all on. background data and auto sync enabled. the screen has been on almost the entire time. current battery? 40%! that's with constant interaction, at times, I was playing games and listening to music at the same time. I mean Im using this phone to the max and its performing incredibly.
in real life, I will underclock to 1 or 1.2ghz (still an underclock since the system is clocked at 1.5ghz default) and wont have the screen on the entire time, so I shouldn't have a hard time making it through a day with moderate to heavy use I also never really use BT and wifi is a rarity. background data will likely stay enabled, but we'll see.
please excuse grammar, on the sensation right now and I just gave up the BB 9700 keyboard just two days ago, one of the only good things about that phone!
edit2: okay so I ran down the phone. it shut down just minutes before the 3 hour mark. this is very exciting because my battery barely decreases while the screen is off. on Max brightness and wifi/GPS/Bluetooth/4G on, and the screen on for all but about 10 minutes, I got about 3 hours. this is exceptional. ill do a real world test tomorrow and report back, but things are looking up. currently, brightness is set to auto, wifi is off, GPS and Bluetooth are off, processor is clocked at 1.2ghz. very excited that this one calibration actually did something!
also, I consider HSPA+ to be 4G cause its about 10 times faster than any 3G out there and it's actually been official for a while.
www.phonearena.com/news/ITU-says-LTE-WiMax-and-HSPA--are-now-officially-4G_id15435
Edit3: It helped, but I'll be buying a Chichitech battery, ordering it tomorrow. 1900mAh better make a difference.

So its been a few days, but here's what I did to get acceptable battery - all at once:
Flash a Cyanogenmod rom, HyperSensation, the other one, Selfkang or whatever is a MAJOR battery destroyer for me. Any kernel, any clock speed, I'd lose 5 to 10% an hour just idling. I lost 15% alone playing 4 mp3s through my AUX cable. Not saying it's like this for everyone, but it was for me.
Flashed Faux's kernel, Joe's RCU from his thread.
Underclocked to 1.08Ghz while the screen is on, 540Mhz while the screen is off.
Undervolted the processor using FauxClock to -37.5mV, might go even lower if it's stable.
Ordered a 1900mAh ChiChiTech battery from Amazon, http://www.amazon.com/CHICHITEC-T-mobile-Sensation-Cellphone-Battery/dp/B0057US9YW - whether or not it's 1900mAh doesn't really apply, but what does is that I instantly got 20% more and I'm not even done conditioning. It's only 23 bucks, two for thirty. I was so anxious to try to get a battery that I next-dayed it for 17 bucks.
I'm a moderate to heavy user, I used some wifi hotspot today, automatic brightness for the display, background data and auto-sync, listening to standup comedy mp3s for 1.5 to 5 hours a day, web for probably 30 minutes to an hour a day, and today specifically, 45 minutes of Legends of Yore (fun rogue-like!) and 15 minutes of Age of Zombies.
Only two thirds of my battery used and I've been off the charger for 13 hours. My old battery would have given out about 6 hours ago, and that's if I cut my activity in half.
Anyhow, problem's solved, but I figured it'd be a good read for anyone in a similar boat.

[Q] Battery Life, Return Or Not?

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?

Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

Well if you do root than TPC's Rom is the best. It comes with kernel and the battery life is outstanding.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.

I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!

This is my first smart phone, after 20 plus years of having cel phones. I try to read before posting any questions.

good habit to get into thanks for that....the search button is your friend.

I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...

Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.

Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..

I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

Battery Life - What Can I Expect?

A new Nexus S user here...
I'm coming from the HTC Liberty (Aria), which I could expect to get two full days worth of moderate use from.
I have 3 email accounts - one exchange account that syncs every 15 minutes in peak times, 2 hours in off-peak, and two personal accounts that sync every hour. A weather widget, Google Reader widget and that's about it. Battery stats tell me I usually have an hour and a half of screen on time a day, with maybe 45 minutes of browsing. I'm lucky to make a phone call a day, and maybe a dozen text messages.
I bought an HTC Raider, kept it for a week, and found I had similar battery life... but the headphone jack suffers from a hardware issue on that model, so I sold it back and tried a Galaxy S2 LTE. I was lucky to get 7-8 hours of life on that phone, and after fiddling with 100 options, I sold it back and have now ordered a used Nexus S.
With my usage above, and any necessary kernel/radio tweaks... what can I honestly expect for battery life? I ask because it's really a deal-breaker for me... if the Nexus S can't give me at least a full day's worth of juice with that usage, I'll wait to see reports on the Nexus 4 and go there instead... but I'd prefer to keep the difference in money.
DON'T SUGGEST ANOTHER PHONE, PLEASE.

I usually charge at night now, and often have a chance to charge for an hour or so at work. But I still would like at least 16-20 hours of usage guaranteed. I'll be happy to buy an extended battery if that helps too, but not if it increases the phone's size!

There's no extended battery that won't make the size bulkier.
On "decent" usage, meaning you're not playing 3D games, you can expect around 3.5-4 hours of screen on time.

I've seen a couple of 1850m batteries on eBay that are stock size?
Also - I do no 3D gaming - occasionally I get sucked into Draw Something, but that's it.
With the GS2 - I was getting 7 hours of idling time - screen off, no apps running, etc.

They're bull$hit.
That's terrible idle time. If I don't touch my phone and text very little with no 3G (my 3G plan is just too expensive) but wifi on, I can get well into the 1 day and a half of idling without any problem.
It's mostly the screen that takes the most power on the Nexus S.

I have found my battery to be much better while using an auto brightness app like Juice Defender or even better LUX and keeping my LCD as low as possible (usually -50 while inside)

If you are buying extended battery, make sure it has REAL mah like nexus s battery. Some battery are deacripted like 2000mah and are fat, but they have 1300mah.
You can get 3-4 hours of screen on time with moderate use, it will last about 9hours from charger. You should be ok. If you have gingerbread you will get even more uptime.

Well, I'll want to get on at least ICS - no sense upgrading if I'm going to stay on an old version of the OS in my mind. I think if I could find a genuine 1850mah battery that would be enough. If I can my whole work day (usually 9-10 hours) and come home with 40%, I'll be happy enough. It sounds like that's very possible with this phone.

You won't be able to find a longer lasting battery unless you're willing to have a thicker phone. What you can do however is have a spare battery and a charger that charges both your phone and that battery at once.

I'm actually thinking that's not a bad idea either. I also have a solar battery that right now gives about 4-5 hours of extra juice to my Liberty... so I'll bring that with me on outdoor trips at least!

try some kernel/rom combinations to improve the battery and have complete charging-discharging circles in the begining.Now i m using AOKP milestone1 rom with trintity kernel and i have approximately 1,5 days with prety decent use including games and wifi,and data enabled at least 3hours each

What Trinity version?

Average screen times:
GB - Not sure.
ICS - 3.5-4.3 hours.
JB - 2-3.5 hours.
Nexus S (GSM i9020a)
Euroskank AOKP (Build 5 - 4.1.2)
Matrix Kernel (24.0 - CFS)

Wheatly (Screen Off) (400/100)
Deep Idle (N/A - Deadline)
BLX (N/A - Inverted Apps)
Black Exodus (Stock Voltage)

this phone does magic when it comes to being idle, i have gotten up to 1 day and a couple of hours on 3g idle....screen time really kills the phone especially when browsing the web or listening to music for long periods of time:/ but overall great phone for the size and everything.

Yeah - I'm almost more interested in good idle time over screen time.

Idle time I can pull 2 days no problem. On 3G network but with data disabled though, I sync my stuff manually.

If you are into idle time, I can tell you that I get a total of 4 to 5 days, but that means I don't touch it at all and 3g is disabled.
I'm using CM10 with minimum screen brightness.

i am personally NOT impressed by the Nexus S battery life, and i dont even have 4g. maybe a full day if you dont use it at all. I have used about 4 roms over the past year, using air kernel right now and its okay. fast charge is a lifesaver

Battery life getting worse, common problem?

Yesterday a post was made to /r/nexus5 on reddit about how battery life was getting worse as time went on. Over 100 people replied saying that their phone was getting worse battery life as well. Here's the link: http://www.reddit.com/r/Nexus5/comments/1yxj2g/battery_life_went_from_insane_to_terrible/ The most people were able to find out was that there was a problem with the Android OS process. Are you guys having similar issues? And do you have any fixes?

Batteries do lose their max charge over time. We're now 6 months aged for the first purchased devices, so it could simply be those batteries are starting to age. They still have years to go, but a brand new battery will always be impressive.
It's one reason why I silently laugh at people bragging about great battery life for a brand new device. of course it will get good life, it's a new battery running optimized software that isn't pushing the hardware as hard as the software 2 years into a device life cycle.

posted by people that know nothing..
as time goes on, you install more and more apps. many apps arent coded very well, and have other issues. anyways, people get more and more of these crappy apps that will drain more and more battery without you even using them. anywho, not a problem here. i get pretty much the exact same battery life now as i did months ago.

great battery life for an "old" device, 5-6 hours screen on time every single day. the batteries life doesnt reduce that quick, and generally youll change phones(within 2 years) before you see the life of your battery shorten.

6 months isn't going to be noticeably less max charge unless the battery was severely abused. Also the phone has been out for 4 months and most are younger.
Here's something to think about: Usage patterns change. People install new apps.
Sent from my Nexus 5 using Tapatalk

Indeed usage patterns play a massive part. And some of which can be completely out of your control.
At home on WiFi I'll get 6-7 hours of screen time.
At home on hspa I'll get 5-6
At work on hspa I'll get 3-4
So at worst case scenario I can lose half of my normal battery usage just based on the carrier performance.

I get about 3-4 hours SoT daily... If anything, that has gone up since I got my device (one of the first batches shipped in US).
I wish I could get 5-7 SoT, with numbers like that, I'm beginning to think I'm doing something very very wrong
Point is... I have one of the first phones shipped out, and my battery life has stayed exactly the same.

High battery usage by Android OS is probably good indication that there are some wakelocks. It has nothing to do with battery being "older".
My battery is great from day one.
Captain obvious mode now:
Posting SoT is pointless and proves nothing. It really depends on what you are doing when screen is on. It is really obvious that it is not the same if you read some book with 5% brightness or play a game.
My SoTs go from 2h up to 7h, depending on usage...

wake lock is main reason makes battery drains so much. try to use greenify to hibernate apps.

LOL. Yep. Give me a day and I'll show you screenies of ten hours of SOT. It'll be BS because to get those results I have to set my phones brightness to less than stock. I also have to set screen timeout to 30 minutes. As well I need to remember to turn the damn screen back on after 30 minutes. I also have to make sure my phone is in my sock drawer doing nothing when the screen is on. It'll still show 10 hours SOT though.

Yeah, the common problem.... My battery just is used for 5 hours.
But there are some fixs to follow:
http://forum.xda-developers.com/showthread.php?t=1168036

I posted my usual screen times on a typical day for me.
Typically I do the same things which are a lot of xda and viewing the verge and YouTube. A few calls and texts.
And from my experience the difference between being at home with WiFi off and being at work with WiFi off is that my battery usually lasts nearly twice as long at home.
I was trying to get across the message that your carriers signal strength plays a massive role on how long your battery lasts.
So say if a mast went down and you get bumped onto one a bit further away (they don't rush when fixing these things unless it's a critical one). You would have done nothing and all of a sudden your battery life has started taking a massive hit.

I'm also having this problem with the android os draining my batter And this started happening within the last week or so.I used to be able to easily get about 30 hours out of my phone, now I'm only able to get about half that. As you can see in the 4th pic, android os has been the cause of a 3h45m partial wakelock, which doesnt seem right to me and is probably the cause of most of the battery drain. the last 2 pics are something that also seems weird to me, as google accounts manager shouldnt take 4% in about an hour. I dont even know why its running that long. Though i know how to quick fix the account manager drain (simply disable it) the android os isnt that simple as i dont know how to see exactly what apps or processes are making it cause a partial wakelock.
Im on omnirom using chaos kernel 9.2

I had a similar issue a while back, and in the end it was Google location reporting within Google now service. Try to switch location reporting off but leave location history on and see if it helps. Also choose Location mode to battery saving.
Turning off location reporting does not affect Google Now functionality...
It can be something else in your case, but this problem was common...

One thing I've noticed as a weirdness is the cache of a phone can get stale and so it gets into some weird loop that drains battery or something and clearing the cache improves battery life. Also sometimes apps can develop bugs or new wakelocks when you do an update so sometimes you have to stay on top of it to track it.

If I did not use some preventative measures to prolong battery life I would maybe get 14-16 hours in a day of usage, I always left wifi on, bluetooth even when not connected, data, force LTE, etc. I did not care because I charge my phone every night. I just find it silly if I get a day usage out of my phone and it is at 50% well assuming you use the phone the exact same as the last day you will use another 50% and it will be dead by the time you get to your charger.

[Q] Battery

Hi All
I'm set with money ready to buy the Nexus 5 ( 32 GB ) or Z1 Compact
And I wonder how well the battery of the N5 performs in real life
Because...when I buy the N5 I don't plan to leave it at 2.26Ghz...in fact I even plan to underclock it to 1.7Ghz ( Because Xperia Z has a 5" and is clocked at an even lower speed and still performs well )
And I'm a light user...who never or rarely uses Wi-FI and am always on 2g ( I never use 4G or 3G ) and always on 5-10% Brightness I also plan to remove all bloatware ( except Google Now ) my phone usually sits on bed and I only get it out to watch some 720p Vids then it rests again
Could I get a day or two out of it and is the "Camera Draining the battery issue" fixed on the 4.4.2 Update?
and finally i just wonder up to now why Z1c gets higher scores than N5 I mean N5 is clocked at higher speeds could this be the effect of Thermal Throttling
Thanks alot :good:

Please Help

Well, nexus 5 will give you a day backup easily according to your usage
The camera bug is not yet fixed, but there are rumors for 4.4.3 update which gonna fix it and gonna release soon
You need to fairly choose between fast updates(nexus and gpe series) or more hardware features (all other smartphone)
If you are interested in rooting and customizing stuff, then you will get plenty of those in nexus 5
Even my usage is similar like you, I use 3G, I do get one day battery backup
I hope it helps you

I'm not 100% sure on the compacts specs but my friend has the Z1. It's exactly the same processor and clock speed. Apart from the camera is awesome and it's waterproof. But u get a crappy sony ui. And Sony updates (which to be fair it has just received 4.4.2) but in my past experience of owning Sony's as soon as their next phone is released they forget about the previous.
The nexus on the other hand is far smoother and faster to use and WILL get all the latest Android releases first and always. And no bloatware. Just fast smooth simple Android
I was deciding between the two before I got my Nexus, and to be fair i don't think I'd have been disappointed in either.
And yes you can easily get 2 days out of the nexus.
Sent from my Nexus 5 using Tapatalk

Ahh because I was a bit skeptical since I checked the GSMarena website and battery endurance was at 40H and Z1c is like 65H
How about the overheating issues?

From what you describe as your usage I can see it lasting a day no problem, perhaps 36 hours, maybe more if you let the battery go down far. My Nexus 5 typically burns from 100% to 70% over 10 hours from when I leave to when i get back from work, and thats on 4G/3G with decent to fair signal, bluetooth on, wifi on, and brightness all the way up, with texting on and off through the day. With minimum texting once I made it around 85-88%, little over 1% an hour.

That's great to know since I even plan to Underclock the phone and leave the other connection options off at most times
As for Google Now without net would it still work or just show "Cannot Reach Google at the moment"

I would say most people running on stock everything will NOT get the stats you're getting.
About 3-4 SOT is about average I would think, and that is with brightness at a lower setting. Don't give users a false sense of security, as your stats are far from the norm...

3-4 SoT hours is already more than most phones could hope for.
6-8 hours SoT is achievable on stock, with lighter usage and mostly WiFi. I wouldn't say it's misleading to expect 6 hours SoT as that seems to be what most users on here are settling down with.
Edit for obligatory proof: Take today for instance, 3 hours SoT with 54% battery remaining. Heavy data usage and loss of signal included. Stock and unrooted.

It shows what is possible. And the battery life thread can show anyone how to do it. Its not hard. Turn stuff off. Toggle it on when you actually truly need it. It isn't that inconvenient.
Yes, you are right about the average times ...the problem is some, like a person in this thread we all should know, complain and complain and complain about their 3 hours screen time. Meanwhile, everything is on, they're gaming, using auto brightness in the sunshine...etc...etc...
As you said, 3 to 4 SOT is average I'd say. If that disappoints anyone....do something about it....there's a battery thread full of help....or sell the phone and buy one with a huge battery that can handle everything on and give you more hours.

That's true, on wifi, the battery life really shines. Out in the real world, with varying signal strength, I would put the average around 3-4 SOT with everything on however.
