Battery is absolutely garbage

Am I the only one?
I upgraded to a native android device from a modded HTC HD2 to hopefully have a longer battery experience.
This battery is absolutely trash. My 2 year old HTC HD2 running Sense Android Non-Native ran at almost exactly the same.
I tested my HTC HD2 side by side with a close friend who has an Evo 4g.. Both Devices still being HORRIBLE in battery life performed almost IDENTICAL.
HTC HD2 is TWO YEARS old, why is it so close in performance to our device..
I love the phone in general, it's snappy (once i removed all bloatware).. Boots fast, runs nice.. i have very few complaints about it.
But how does an 1100 MaH battery run the SAME as an 1600 MaH battery?
I thought technology is supposed to improve, but my non native android phone ran almost the same as this one. Took longer to restart/boot up, but general speed is the same, larger screen size.. similar settings, and same battery life. Pisses me off frankly.

That's how I felt. hopefully we will get rom's or gingerbread on this phone soon that will improve battery life. And by gingerbread I mean the leak from Samsung for the i9000. I've been reading reviews and it seems like it Greatly improved battery while speeding up the phone a lot.

I have to disagree. I've owned may android phones including the evo. This phone has the best battery life in my opinion. I can easily make it almost all day with use without charging

Well like I said, i admittedly abuse the phone.. but I'm comparing to other phones getting equal abuse. It stands up about the same, better yes, but not by much.
If I'm barely using it however.. let's say, mainly just texting, yes it will last all day. But that never really happens.

I love how people admit that they "abuse" the phone all day and then complain that the battery life sucks. If you're going to use your phone that much, bring your usb cord. Or strap a battery pack to yourself and plug it in for "all day" use and abuse.

It's the screen. If you want the super amoled you have to put up with the battery.

What i don't understand is that why the Droid x which has similar specs to our phone can go up to 10 hours of continuous web browsing when our phone/vibrant can only go up to 4 according to tests. Is it because of the screen? If it is then that's just stupid.

It was horrible for me at first, but I then realized the system has to calibrate the battery first. I am getting about 16-20 hours with moderate usage now, which is better than the G2 I had before.

My g2 can go up to 28 hours with light texting and 2 hours of web browsing through wifi and 10 minutes of calls (manual syncs and low brightness also). Once I use the gps and browse through hspa, it's a different story. My sister has a SGS4G and her battery seems to drain faster than mine.
Oh, and if I keep my phone charged for a while after reaching the 100% mark, it stays at 100% even after 1 hour of heavy browsing and watching videos. I think we should all just assume that the battery meters are inaccurate.

I use juice defender and put my brightness setting on auto and I can literally go all day with "abusing" my phone.

let the phone die, to the maximus. meaning once it turns off, turn on again until it doesnt turn on anymore. Now fully charge it, once again when fully charged restart the phone and charge it to 100 again. then let it die again, and full charge. should be fine then

i bought a 3500mah extended battery for my phone. the battery is designed to work with vibrant. it really made my life a lot easier.

I noticed if I set the phone to GSM only, battery lasts almost twice as long. If I'm on auto select (WCDMA/GSM), it lasts from 7AM till about 4PM.
But then again, I don't have a very good 3G/4G reception (or 2G connection for that matter), so my phone is probably working extra hard to find signal all day long.

The new Bali Kernel has shown tremendous battery improvement on my phone. I'm really impressed.

Same here.
I used to only have dark wallpapers and take all the other extra steps for my battery to make it through the work day, and as soon as i got home i had to charge it.
I'm now running fireflies live wallpaper, abusing the phone a little more then what i used to, and i still have battery to spare, not by the time i get home, but by the time i go to bed!!

i also have installed bali. seems to do well, as said its all about the brightness.

My problem with this phone is that wifi uses way too much battery. I have it to turn off when phone is asleep but i'll have the phone at 100% with wifi on. Put it on sleep. 4 hours later. battery is at 65%.
If i have wifi turned off. Battery will be at 98%.

[Q] Infuse Display taking up 95% of battery usage

As someone who was looking to extend battery life, I downloaded "Battery Widget". After 9 hours off the charger and maybe 2 1/2 hours with the display on, I looked to see what was using up the battery the most. Everything from the OS to web to Wi-Fi was at no more than 2% but the display was at 95%. I know its a huge display and its going to use a lot of battery but is this much normal? The battery was dead in about 10 hours.

Sounds like you have the brightness up on it, I would turn it down a little if you have not done so already. Mine is on about a quarter brightness and it is only 79% and the battery lasts the entire day.

Are you on stock ROM? If so, you may want to consider flashing a custom ROM. When I flashed Infused ROM, my battery life significantly improved. And I am not exaggerating... I would drop 100 > 90% in about 5 hours before, now I can easily go 9-10 hours from 100 > 90% with light use.
Regarding display, please see this thread which may help with that:

My screen was on 100%. I changed it to 50%. Hopefully I will see a difference.
I am on stock ROM, however, I've been looking alot into Infused. This is my first android phone and I'm a little weary of custom ROMs being buggy. But of course those fears are pretty much unfounded since I've never seen a phone with a custom ROM in use.
BTW, thank you guys, or gals, for such quick responses.

I understand your concerns and if you are not comfortable, do not do it. However, I can say that the Infused ROM works much better for me than the stock ROM and I highly recommend it. It is much faster and better on battery. I can tell you that the version of Infused ROM I am on is not buggy and much better than stock. Cannot say anything about the latest version since I decided to stay on a previous version because I am so happy with it.

with your brightness up to 100%, i'm not surprised your display eats so much battery.
i'm still on stock and i used to run my display at 50% all the time. then i turned it down to 0% and i still have no issues seeing the screen in any kind of light, even outside. i only turn the brightness up to 50% when i'm playing a game or watching a video.
try 0%, you'd be surprised!

I have the nexus S and the Infuse. You're right, for some reason the Infuse Display percentage is WAYYY high!! My brightness is usually at 50%. But the Display is the cause of 90% of my battery drainage. It's very weird.

Okay so an update.... I've had my screen on 0% for the past couple days and I installed infused a couple of days ago as well. I haven't seen any kind of improvment. ( display is still in the 85%-90% range of battery usage.) Is it possible I just have a defective phone? I love this phone and but im really frustrated with havung to keep an eye on how much juice I have left

No I'm not watching videos. Just using the web, words with friends, messaging, and messing around with the home screen.
A little more info...... last night I unplugged my phone from the charger at 4 am with 100% charge. When I woke at 8:30 am it had 97% charge and said the display was causing 37% of the drainage( I hadn't touched it since 4:00 am). At 8:40 I started playing around on XDA app and, starting at 97%, after twenty five minutes I'm now down to 88% battery with the display causing 80% of the drainage.

It is all a matter of how much you are using your phone and how long the screen is on for. It is not unusual for the screen to eat up 75% or more of your battery power if you are contastly turning the screen on or viewing things on it.
My display is sitting at around 80% right now, and on my old Nexus One, it was usually around 78%.
I don't take personal calls while at work, so almost all of what I do with my phone while at work keeps the display on constantly. I do text and check websites that are blocked at work as well as conduct all personal or financial business using my phone.
Things like calls turn the display off and other things like streaming or playing music will let the display time out and keep working.

The things you are doing are not processor intensive, wifi intensive, radio intensive, but do work the screen.
Are you running a live wallpaper?

No I'm not using live wall paper. I understand that the display is going to use a lot of battery. I guess what I'm asking is it normal for the battery to go down 10% points while looking at Xda forums for twenty minutes. If its normal ill deal with it but if its not I can still take it back and replace it. And thank you all for taking an interest in this thread.

Actually my experience is that the XDA app has some sort of memory leak. It takes a long time to load for me and crashes about 20% of the time for me. I use the browser most the time, and find it is very well optimized for smartphones.
And yes, your battery use is fairly normal if you aren't gaming, phone calling or downloading. In fact my use is at 87% for the screen. But still, I have 70% battery left and only an hour more of work.

I am not sure if I can explain this properly. I am not a word person.
What you see is a rolling average. If you were to not use the phone at all. Let it sit completely idle without firing on the display. You would see that the display is using a low to zero percentage (of course you could not, in fact, see that). You would find that wifi or 3g or android system (or some other task) are at 95% more or less.
The display being the most power consuming component on the device will make a dramatice change to these percentages the moment your fire it. Turning on the display simply to check the battery stats will have run the display's battery percent far higher than the others quicker than you can probably even get to the screen to check the stats.
Keep in mind this is a rolling average. It does not indicate fault or that the display is CONSTANTLY drawing 95% of the battery. It is just using 90% more of the the battery than something at 5% when it is in use.
One should chalk this up to completely normal. Make a poll if you want. You are likely to find near 100% of respondents will reply that display is highest in their stats (unless they have some kind of accessory or something that draws more power)

Nexus S = TFT LCD
Infuse = SAMOLED
To reduce battery drain from screen...use more blacks. Black on SAMOLED screens are actually pixels turned off...while TFT LCD and retina displays jave a pixel displaying black.
Hope this helps put more into perspective.

Battery Life, Oh?

I think it's crazy how many people are downing the battery life on the Sensation. I used my phone a bit today. Off the charger at 10AM, used GPS to go to work with Bluetooth activated as well. Forgot to turn them both off while at work. I used my phone like ever 5 minutes checking Twitter updates(also weather/news/facebook/email/etc updates are automatically updating as fast as the app allows. So quick updates for all my apps, GPS and bluetooth turned on all day. Home around 5, watched a few episodes of South Park on Netflix with my phone. Read some news. Played a few different games for about 5-10min each just trying out new games. It's now almost 1AM the next day, and I'm above 40% battery life. I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all

I have only had my sensation for about 5 days and battery life is amazing! Im still stock too.. I came from an evo 4g rooted running cm7 and or miui and battery life doesn't come close to being as good as my sensation. Not only is battery life awesome, this phone is awesome. I moved to Southern California a couple weeks ago and Sprint out here is horrible.. so I switched and couldn't be happier. Plus I like this phone was better than the evo series. Battery life is sweet!

You would have to post a screendoor shot of your battery usage and screen on time to completely determine how much the phone was used and how long the screen was on.
Bluetooth and GPS don't use any battery or have low usage (depends on the chipset because some completely turn off) during standby since they're not being used at all.
So we can all praise our phones for having good battery life, but it all depends on usage. If you don't use your phone a lot (you could turn on your screen every 5 minutes but at the end of the day have only like 45 minutes of screen on time and like 70% battery left.) Then you get good battery life. Use your phone a lot and quite simply battery life sucks.

I think it can largely depend on how you use your phone, not just how often or for how long. For example my Fiance also has the Sensation and on her first charge she got 3hrs52minutes before hitting 10% battery. Since then she has only gotten ~2hrs each day now that she has Twitter and Facebook for Sense accounts set up.

That's not good. There's gotta be something wrong with either her phone or something. 2 hours of battery life warrants an exchange.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.

If I do what u did, my batt will be flat in 6 hours. Somethings just not right with my sensation.

You can go by statistics and on screen time and what not. but I just got home from work, and I literally used my phone for about 2 hours straight calling carriers for a customer. I'm above 80%. So from 9AM-4PM, only saw a 20% drain. Once again, keeping BT and GPS on just to see how it goes. ALL of my autosyncs are once again, on, and set to the most frequent can be.
Compared to any other stock phone, this is amazing. Compared to my Cyan N1 and my Cyan NS, it's not a huge difference. Although, at this rate I may give the lead to the Sensation, since I'm leaving all these extra features on throughout the entire day.

good
I get two to three days out of my Sensation, and I'm a relatively heavy Internet user... don't phone much.
At first I wasn't getting great mileage - having to re-charge after only 10 hours or so, but did two things to improve it dramatically...
First, charge the battery once using the following method:
1. charge battery to 100% and leave on charger for an extra hour
2. unplug the cable, turn off* the phone, and plug the charger back in. leave charging for another hour.
3. unplug the phone, turn it on for two minutes, turn the phone back off*, and plug in the phone again. leave charging for another hour.
* when I say "turn off", I mean completely, without fastboot. so either disable fastboot before switching off, or turn off the phone and pull the battery then put it back in.
Second:
Turn off automatic screen brightness, and set the brightness manually to what you need. Ideally, I'd like to have an auto-screen brightness adjustment that automatically sets it, say, 25% lower than what the built-in function does.

That's pretty exceptional. I usually get 13-14 hours with 5+ hours of screen time before I'm at 20%. Using the chichitec battery, btw.

My chichitec battery went 18 hours yesterday before it got to 10% and I charged it. That was with a lot of web browsing, some phone calls, music, games. Id say, medium-heavy usage.
Matt

Same here I have had several Android phones with different carriers and this is hands down the best, on par with the iPhone I had previously with Verizon. No problem getting through the day with Exchange and 2 IMAP accounts and heavy phone use, the only mod is I set screen brightness, battery is stock.

no one is complaining i watch sparticus on netflix and game of throne on hbo go for 5 hrs straight while facebooking random hoes . and i am out of battery..
we are complaining that the 4g drains the phone while on idle.

this is the best battery life i've ever had on a phone. i can't complain at all... i even have gps on and i could never do that before. lol!

Guys, having GPS on doesn't use any battery. It only uses battery when it is active. So for most of you 99% of the time your GPS is off aka standby or whatever you wanna call it.

One reason many people complain about bad battery life is that it seems some Sensation models are actually faulty. Best evidence: TechRadar review.
http://www.techradar.com/reviews/phones/mobile-phones/htc-sensation-943466/review?artc_pg=9
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.

let's talk battery..

so as it may be known, i came from an iPhone 4S and traded that for an HTC One X, i've had it for a little over a week and i really like it a lot BUT (you knew that was coming i think..) the battery is below par, i get about 3, on a real good day 4 hours of usage from a full charge. i only auto sync mail, screen is on 25% (also tried auto for a few days), when at home it's connected to WiFi, data off and when i go out the other way around, GPS and Bluetooth are off at all times. the main thing i do on my device is Twitter, Google+, Facebook and Instagram, + some light browsing the Internet. i understand the screen and processor take quite some battery but it's not cool to only be able to use the device about 3-4 hours before running empty. emailed the guy i traded with and he said he got about 7hrs, which would be awesome after dealing with 3-4 ;}
i am using Nova Launcher Prime, but prior to that when i ran Sense the battery was about the same. may just revert to stock to see how that will affect the battery, even though i will miss my widgets and setup. i also emailed HTC and was considering going to AT&T but since i traded the device i doubt they'll be much help.
what do you guys get... and what if anything did you do to improve it ?
thanks.

How much screen on time? 4 hours is nuts. I easily got 24 hours on stock, with light usage, maybe even a day and a half. The 2.2X versions firmwares seem to get better battery life. Just this morning I had just under 50% battery left after 24 hours, with 1 hour screen on time.
If screen brightness in on "Auto" turn that off, and set it to something like 40-50%. That should save you some, but doesn't account the type of battery drain you are talking about.
Might be some runaway processes. Or any possibility you are in a fringe LTE area?

on screen time is what i was reporting, round about 4 hours -which yea is pretty horrible i'd say. i even have the screen brightness lower; 25%. checked the processes and for what i know nothing out of the ordinary, but i'm a novice Android user so.. prior to yesterday i only used 4G when out, so at home i stayed on WiFi.
battery stats now:
- 76%
- 5h 8m 54s on battery
- screen on 59m 28s

Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

Your stats are very normal for this phone model. The One XL screen is gigantic, but isn't AMOLED and as such uses much more battery life to power than some other Android devices. I get ~3 hours of screen on time in a days use of battery, and that is about 10-15 hours away from a charger. From what I can gather of your usage, if you are looking to extend your battery life, the only thing to do is leave the screen off more.
Do you flash custom ROMs? If so, try a custom kernel that allows you to change the CPU governor and clock speeds. The processor in the One XL maxes out at 1.5GHz by default, but you can underclock it to 1.2GHz with no noticeable detriment to performance. Also you can set the minimum frequency to an even lower clock speed, which allows the phone to use even less power when idling. Finally, make sure that the CPU governor is set to Ondemand. Powersave actually doesn't save as much power as you would think!

my favorite part was when he compared a tiny 3.5" screen to a 4.7" screen and expected the same battery life, even though it is roughly the same

Firstly, 4 hours screen on time isn't bad at all. I'm sorry your only reference is an iPhone.
To get 6+ hours of onscreen time with this phone like I and many others get you will need to do two things. Firstly, flash a custom ROM. CleanROM 4.5 is a good one that's as close to stock as you're gonna get. The second thing you need to do is turn off auto brightness. Leave the brightness set at 35% - 40%. This will improve battery life immensely. And no, 40% brightness is not dim.
Happy flashing!

10-12 hours up
5hrs 15mins screen on

Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

with my iPhone (GPS on always, WiFi always, screen on about 70-80%) i got an average of 6 hours with peaks of 7. 4 hours with the HTC One X is on a good day.

i did not flash a ROM since i can not unlock the phone (yet). where i compared, referred to the iPhone is based upon the previous owner who said he usually got 6-7 hours on screen per day. it's uncool that people not live by the rule if you don't have anything nice to say, don't say nothing... i'm only trying to get some help here (luckily most members are helpful... i'll try and ignore the others) and my other reference would be a BB Storm, which lasted very long, but the device wasn't very exciting
i'm following the thread where rooting is discussed but i believe there's little progress. AT&T is also not pushing Sense 4.1 (yet, mine has 4.0) and ICS 4.0.4.
just spoke with HTC and they agree it's too short and are willing to exchange battery... downside i would be w/o a phone for 7-10 business days. might swing by AT&T and discuss, "issue" is i was not the original buyer.. he (HTC rep) stated they might give you a loaner (i doubt it..) we shall see.
thanks to those with positive feedback.

so far..
click here for today's results --16% left.. slightly over 3hr on screen time.

It really depends on how you use your phone, and not all screen-on time is the same. 4 Hours is screen time is pretty good, and pretty on par with what other users on here have observed. The phone is new to you, so I bet you are using it like crazy. If that use includes a lot of internet, playing video, or games, its going to use more battery than some other activities. I don't know if a replacment is going to make you any happier.
You also have to consider, aside from a much larger screen, its also much higher resolution than the iPhone. Pushing all those pixels by the GPU takes power. The CPU is also much faster than the iPhone (and just about any other smartphone except the Galaxy S3), again using more power. Screen time may be less, but its doing so much more in that time.

4 hours, if I made would be somewhat acceptable, yesterday I had a little more then 3. I do not play game, I manly do social media & a little surfing..

my battery would last over 24hrs until the OTA 2.20 update now im lucky to get 12hrs out of it. Did they change something in the update?

The 2.20 OTA has an new radio. So its possible that the new radio happens to result in worse reception (and therefore battery life) than the previous one. Newer radios do not always get better results for all people, as its very geographically dependent.

Thank you for the reply and yes the radio looked like it was a new one and in PA i dont get that great of service everywhere.

Yeah, 4 hours of screen on time is normal so I definitely don't think you have any sort of defect. Signal strength also has a lot of impact on battery life. Keep brightness as low as possible while still being comfortable to your eyes (battery life isn't worth putting extra strain on your eyes). I use an app called display brightness that allows you to change brightness by swiping across the statusbar. I keep mine at the lowest level and just swipe a bit to increase it when I need it and then swipe it back down when I'm done. A custom rom could help some. If nothing else, root so that you can use something like better battery stats to give you more info on what's happening behind the scenes so you can make some adjustments. Although I'm not one to push using this, you might want to install something like juice defender to see if it helps. Verify you don't have some app running in the background unnecessarily chewing up cpu use. Note though that just because an app is running in the background doesn't mean you should kill it. As long as it's not doing anything, it's better for it to be running than to have to load it up (especially if it's an app you use frequently). A couple of other things to verify, don't use push notifications / syncing (I keep background syncing off a manually sync (well, I use Tasker to sync things at different times of the day)). If you can, use wifi. If wifi isn't available, turn it off. Also make sure wifi notifications are off and that you aren't using 'best wifi performance' (both under wifi advanced settings).
I'm sure there are some others I missed but hopefully these help and at least give you a starting place. No matter what though, enjoy your device and don't obsess too much with the battery. Once you've gotten over the 'new toy' syndrome, you should get a days use out of it. I pretty much take mine off charge in the morning and put it on charge before going to bed with around 30‰ left. Sometimes more, sometimes less. 3-4 hours average of screen on time, 30-60 minutes of calling.

Np. Been using it since early on and it continues to improve. One of those handy must have apps.

update.
went to the AT&T Device Center (did not know it existed until the regular AT&T store told me about it...) they played with my phone and concluded that the battery was draining too fast while using it, so w/o discussion they exchanged it.
got a follow up question since AT&T did not know, with the iPhones i would let them drain all the way down at least and then fully recharge and leave it on the charger for an extra 2 hours after it being 100%, i *think* that helped condition the battery.. anything you guys can suggest anything for me to to now that i have a new device to maybe improve/condition the battery ?
thanks.

Post your battery stats screenshots here!

Ok, I have to admit, I'm not the biggest fan of this phone so far (way too much bloatware, and a little laggy, IMO). But the battery life is effing fabulous. 5.5 hours screen on time with nearly 20 hours screen on time. AND THAT IS ON LTE THE ENTIRE TIME -- WIFI WAS NOT USED AT ALL.
Don't ask me why my "mobile network signal" bar has some black gaps on it. I was not in airplane mode at all and as far as I know I had a full LTE connection the entire time the phone was on.
I don't think I've ever seen 5.5 hours screen-on time on LTE on a stock ROM/kernel before, so I'm pretty impressed.
Info: Brightness manually set to ~25%. This was mostly browsing the web and xda, and using messaging. There was a short call and about 30 minutes of GPS navigation. One Gmail account syncing the entire time. Solid black wallpaper. Most of Samsung's gimmicky features disabled, and most of Samsung & AT&T bloat disabled (see my HOLY MOTHER OF BLOATWARE thread for full list).

Yep I'm very impressed with battery personally. That was my first charge cycle too--it may well improve!
Anybody else want to post? I especially want to know if I'm the only person with the black gaps in my mobile signal bar--that worries me a bit.

I went to bed for 10 hours left it idle with wifi and GPS on it only went down 2% lol

Did you enable force GPU rendering in developer options & cut down the animations to .5 or turn then off try it out should speed ui make things faster try it out if you haven't already

I have turned off animations. Any downside to forcing gpu rendering?

So what is the technique you will be using to cycle your battery? Charge for 8 hrs before powering on. Then drain until it shuts off by itself. Or until it reaches 1-5%? Then power off and full charge? And how many cycles do you normally do? About 3 or?

Or you can just use your device normally as I don't think the battery has a memory.

Dont want to be a negative nancy here.....but given that the screen eats most of the battery, I was hoping for more at 25% brightness. I had the One for a few days, and it was set to auto brightness most of the time (which was pretty generous with the backlight, seemed to hover around 40% indoors except in total darkness, and maxing out outdoors) and it lasted me 5 hours on LTE.

Yeah I am not impressed with the battery figures considering the battery size...
Although that extra 200MHz of clock speed certainly can factor into that and nobody has really dove into what device-specific CPU optimizations each device has.

Fantastic. Nice job Sammy. Looks like respectable battery life!

Went on 16 hours yesterday so thats pretty good!

I made it 1d 1h 50m with 5 hour screen on time (50% brightness manually set) Wifi was on the entire time, mobile data was disabled and gps was on from time to time (10 hours straight at one point) It handled pretty well for its first day, got the phone set up during that time. 1% Life atm

It has a 1080p Super "Power Sucking" Amoled screen, so 5 hours of screen on time is quite good in my opinion.

Impressed myself so far...

Im really happy...watched over an hour of youtube (music festival videos) listened to over 2 hours of music...and general messing around...with everything on default settings...turned nothing off when I got the phone, and have nit uninstalled any bloatware yet...so this is with wifi on, lte on, gps on and whatever other s features are on by default and auto brightness I believe

I could only go with about 3 and a half hours of screen time on my SIII so 5 hours is definitely very good!
