In the story he states that the batter would last four hours? any truth to this? he also explained that there is lag in the sense?
http://techcrunch.com/2010/05/29/htc-evo-4g/
Maybe 4 hours of non-stop web browsing with the brightness all the way up while on 4G. Also, I've never had any lag with Sense.

The battery is is very poor. I'm not exactly sure why that's the case since the EVO doesn't report the screen as a large draw. For example, I unplug my EVO, connect my Bluetooth headset and listen to a podcast for 10 minutes. That drains the battery to 92% from a full charge.
You will most likely have to carry a spare battery to get through the day, with light usage.
I'm hoping its an optimization issue and they can fix the battery issue with an update. Fingers crossed.

hmm, alright i mean this is big for a person who is out 24-7. (arnt we all) i wonder if it has to do with anything similar to what the hero had when it was released.
My battery life is not perfect. But people always have this problem. I was a G1 owner and everyone complained about the battery life when it first came out. And then slowly after a mont or two everybody stopped...why? Because the battery life got better with time. From 5 hours or so to 9 or 10 hours.
Then I went to an HD2. The first week I was so scared I had made a huge mistake because the battery would last about 4 or 5 hours. After I did as suggested and let the battery completely burn out and then completely recharge for about three cycles, the HD2 had the best battery I had ever seen. i could use it for 2 days and have 60% left.
Now I have an Evo. And the first stay (with constant use) it died after about 4.5 hours. But I am going through the process of draining and then FULL recharge of 6-8 hours and I'm sure it will be fine.
People think they plug the phone in an hour or two and it says 100% and they have charged it. My opinion is that it takes the battery a while to know what 100% and 0% are on any given battery. After it cycles through a few times it will actually have a true accounting of the battery life, power consumption.
That is all my opinion and experience. I am hoping the EVO has a similar battery life to the HD2. That would be perfect for me.
EDIT: And as for lag....the guy is obviously on crack and just saying stuff to say stuff. I doubt he even has an EVO. He's reading about Sense Lag on the HD2 which there was some) and passing that information on. Anyone who actually HAS an evo have any lag? I think not.
And if he thinks an iPhone 3GS in ANY way blows the EVO out of the water...he is obviously lying. I mean based on feature set alone. There is no way the iphone can browse as fast (4G...hello), operate as fast (gee isn't that processor almost twice as fast), take better pictures? No. Have a front facing cam? No. Oh yeah...that screen size on the iPhone sure is better than the EVO. WTF?

I understand what you are saying. That was the only reason i am worried about buying an EVO. This author must have had all the applications syncing every 15 minutes. I have an apple itouch not sure how close the phone and this thing is but I like it. It is smooth and quick. (buts its not a phone). When it comes to android... Its about the experience that comes with it.
But this guy is positively being paid off haha

With light usage I had 36% remaining after 14 hours the other day. I think you just need to give the battery time to get adjusted. However, I have noticed that it seems to drain faster from 100-80% than it does from 80-50%.

Well I actually just recently noticed the same about my iPhone 3G. The first 10-15% go really fast.
My evo seems to do pretty good with the battery I can go the whole day without needing a charge but I do charge it when I get home. When I'm using it for games all day it drains pretty quick but at those time I plug it in... I don't know what they expect when your rocking a 1ghz processor, a 4.3 inch screen, and about every type of network connection you can fit in a phone... as far as lag goes on this phone I notice very little mainly when I'm installing like 3 or 4 apps at once... compared to my hero this thing is a rocket! And once Android 2.2 is put on here this thing will be smoking.

My Evo lasts for 8-9 hours. That's 70% idle with screen off. Cell Standby at 40+% is killing my battery.
My motorola droid in the same time still has over 50% charge. There's no question that the Evo is a battery drainer for whatever reason.
hate to say it, but once a fan boy always a fan boy. I used to have a win-mo device (touch pro) and i like it, then i moved up (should i say downgraded) to the instinct- worst decision ever. than i used the android platform on my hero. I'd have to say its leaps and bounds easier than win-mo.. My brother has an iPhone which i always play with when he comes over, and i think its a really easy interface to play with.. thats all. The speeds at which apps were open weren't any better than my hero. I also opened up maps on his phone and mine, and my location was dead on with the hero, the iPhone was 100meters. LOL.
But everyone needs to try other stuff out and make there own decisions, dont let someone who is obviously a fan boy tell you whats good and bad.

thats ur prob ur using bluetooth it will use more battery and then ur playing the podcast at the same time any phone u do that on u will use more battery
the battery technology is a few years old. the cpu is 1ghz.. the phone is sniffing 3g/4g/wifi/bt plus the shiny screen and backlight all use power. the battery technology being used in this state of the art phone is not advancing as fast as the phones are...
the reason the top ~10% of the charge goes so quickly is due to the you taking the phone off charge.. the cells in Li-ION batteries are not created equal. some cells will get a stronger/longer charge than other cells. once you take the battery off charge, the cells that are stronger in charge than the others will feed that extra charge to those other cells, so your battery charge will fall down to around 90 or so pretty quickly out the gate.. from there the cells are all stable and equally charged and stay at a constant discharge rate for about ~87% to about ~55%.
once the charge falls below 55% the cells really start to lose their charge and the battery curve drops drastically.
when you "top off" the phone for , say, 30 minutes or so and you take it off charge and you see 100%. do understand that one or two cells have a fuller (my word) charge than others.. once the cells equalize, then you will see the tru charge (which will be much much less than 100%)...
I'll post my findings here although probably no one will believe me. I'm not a fanboi since i've phones on three carriers.
My EVO will lose 2% per hour sitting idle which is fantastic. My HD2 loses approx. the same amount, maybe a little less.
I've found the EVO to be no more power hungry than any "superphone" i've used including the iphone 3gs.
signal strength also plays a part
one thought based on my experience with a palm pre and htc hero: signal strength.
My office has very low signal strength (1 bar or less). The battery seems to drain quite fast here. If I'm somewhere else with good signal, my battery lasts much longer. Same battery drain if you're going in and out of evdo / 1Rxx.

My battery life is like all the other phones i had lately (see my sig).
No more, no less.
I have to say my battery is getting better with going through a couple full charges, as for lag nope none not here
“Phone idle,” and “Android system” that eat up over 75% of the life.

LMAO, the fact that he wrote that puts severe doubt in his skills to review an android phone.
I can't believe this thread is going on seeing as that's an Apple Fanboy site. Will say anything to make his Iphone sound like the best thing ever. He lost all credibility when he said the Nexus One and Incredible were better phones.

the battery in the EVO (and pretty much every phone evar) is a single cell battery.
you have no idea what your talking about do you?
hello my phone doesnt last 1 day of charge and it says 40% is due to display/screen can anyone help me?

You can lower your brightness if it is not already at the lowest setting.
Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?
I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.
hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...
I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.
sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...
Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.
GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen
hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........
I've owned an iPhone 3GS for almost four years now, and it's time to upgrade to something new. I've decided upon the OGP as my new device, but I have some questions about battery life. I've read a few reviews that said although not as good as that of the Samsung Galaxy Note 2, the battery life is still great. Then again, I've also read a few reviews that have said that the battery life is horrid and that LG phones in general seem to use more battery than most while just sitting idle in standby mode. So, it seems to go both ways, depending on which review one reads.
My typical usage is about 90% browsing and reading webpages, and about 10% watching YouTube video, with a bit of music listening thrown in. With the iPhone I had to keep the screen set at about 50% to get me through a day of the above usage. Sometimes, an hour long recharge during lunch would give me battery life until the early evening. I hated having to keep the screen dimmed to 50%, but that's the way it is with that particular phone's power-hungry LCD. For video watching, I max the brightness so as to get as crisp of a picture as the phone is capable of.
I had looked at getting the Note 2, but I didn't care for the AMOLED's lack of whites and lack of brightness (and low resolution) in comparison to my dinosaur iPhone. If I did get that particular phone, I'd have to leave the brightness at max 24/7 although I don't know how that would affect batt life. Either way, the Note 2 screen did not appeal to my eyes, and the one on the OGP along with that of the HTC One were the best I've found in the larger phones.
So, my questions are, what do most people keep their brightness set to on their Optimus G Pro for most of the time, and how much screen time do you really get at that particular brightness level? And, does it seem that a few people have possibly gotten defective batteries? I realize that the G Pro's screen is an LCD with a white backlight on all the time the screen is lit, and probably won't be as efficient as an AMOLED, but with my type of usage (with the screen set to max) what kind of daily battery life can I expect from the OGP?
Well, I don't know if I can give you an estimate based on your exact usage, but let me share with you mine. I have my brightness set to 65% with auto brightness turned on. For me, that is a nice, comfortable viewing level that is easy on the eyes. I love the colors at 100% brightness, but it's almost too bright for me to look at for long times. Anyway, I only use my phone to send text messages and check web sites during the day, but then I play games in the evening (like super stickman golf). I can get through the day easily with 25% remaining when I plug in at bed time. I get about 4 -5 hours of screen on time out of that, so in total I could get about 5-6 hours if I were to drain the battery all the way.
So that doesn't exactly answer your question, but each person's usage is going to be slightly different. It also heavily depends on what you have for apps that are running in the background.
hmm
I'll say this much, screen is responsible for about 50% of your phones battery drain across the board so if 100% brightness is more important than another hour or two of usage time then go for it. This thing should get you a full day even at 100% charge and relatively heavy usage but get comfy with seeing 20 or 30% by early evening. The hardest thing to get used to is remembering that 20% can still mean 2-3 hours of usage and is not an emergency. Another plus of this phone is you can charge about 50% with one hour of charging (or 25% on 15 mins) so as long as you are using a good charger you can juice up in a hurry.
Dear nexus 7 FHD owners,
I have possessed my shiny new nexus 7 since tuesday last week, and boy am I happy with it. The only flaw it has is a dead (black) pixel in the lower left corner, which is covered by the soft button bar when in landscape.
While it is a fantastic tablet, I consider my battery life very weak. While I dont have exact numbers at hand, using google chrome to browse the interwebz drains the battery very quick imo (ill post on this in the future).
I do, however, have exact numbers on gaming. Yesterday I drained the battery from 100% to 14%, playing eternity warriors 2 for 3h14m straight, With a screen on time of 4h47m, of which an hour at the lowest brightness setting and the rest at 10-25%. Do these numbers seem to you? How much gaming time do you get on a single charge?
Idle drain seems about right, i left it at 88% when i went to bed last night, waking up with a charge of 85%. This is with wifi on in sleep, wifi and mobile network location on, currents disabled and all sync apps set to once/ hour. Though surprisingly when i tested the idle time during the day, leaving wifi off but all other settings unchanged, it drained 5% during my 6 hour school day, leaving the device at home.
I also played galaxy on fire 2 HD for 2h36m straight, draining the battery from 80-1% (i did maybe 10minutes worth of browsing in between).
I should mention that out of the box I had about 50% battery and I drained it to 1% on the first use before the first charge. I know this is bad for the battery, but it is said that most devices get their first full 100% charge in the factory right? Still though, might this have an impact on my battery life?
I'm looking forward to your feedback. The return policy ends tuesday next week, and I can return the device no questions asked until then. I will do that if it turns out my device's battery life is indeed quite the exception. I'm reluctant to do this, however, since I only have one dead pixel and I am afraid I might receive a device which has other or more flaws.
Your device's battery performance is pretty normal on the 2nd gen N7. Games seem to drain the battery the most. I get the same results. 3hrs with gaming. Worms Armageddon in my case. I usually get about 5-6 hrs od mixed screen-on use on a single charge. From what I observe Chrome will usually flatten the battery in 4-5 hrs depends on what pages you browse. The longest battery life you will get on video playback - up to 10 hrs with MXPlayer. That all on autobrightness.
I find these results a little disappointing. At least they are very far away from what is advertised. I do not know what is the biggest drain factor but I suspect the GPU and the wireless connectivity.
While transfering large video files over wifi between my nexus and an iPad it seems that the nexus uses more battery with screen off than the iPad with sceen on.

Thanks for your reply. It is really comforting that it's not just my device. Still considering a return for the dead pixel more and more, though.
RAM Hungry Games
I avoid RAM-Hungry activity. Mostly 3D games of course, drain my battery quickly when I have other services running, and the games that demand a lot of RAM at once will suck the juice out of that battery, so I usually keep it on the charger when playing demanding games.

How quickly does your battery drain when not plugged in though?
wow, such nice battery life, and complaining
Mine drained in about 1.5 days last week with a bit of usage, with wifi on the whole time. Charged from 11%. No sync.
todays results
Today my battery was drained in: 1.5 hour gaming, 1 hour chrome, 5 hours screen on time.
I find these numbers quite the disappointment.

That does seem a little low to me. I don't do a lot of gaming (Tapped Out is about it) but I have a lot of on screen time between Kindle, web browsing and Netflix. This is all anecdotal though, I haven't actually measured how good my battery life has been, it just seems to be good to me.
Are you running a custom ROM? I'm running CM10.2 and I *think* battery life got better when I flashed it. But again, I didn't measure and compare so its just a gut feeling.

I'm running full stock. My stand by time is actually pretty good (1% overnight last night), but thats probably because ive disabled most power hungry features (location, wifi off in sleep etc).
While i do a lot of gaming and battery life is expected to be low then, I expected at least 4 to 5 hours worth of gaming, since it is advertised it should last 9 hours when viewing 1080p video (which is not streamed)

Bad assumption. The hardware video decoder is extremely efficient (at 0% brightness I measured 1.28W power consumption for 720p; equivalent to 11.7h battery life).
The CPU/GPU hits thermal throttling (not enough cooling to run at full speed) at about 5W power consumption (= 3h battery life). Going from 0% brightness to 100% brightness adds another 1.05W (total of 6.05W = 2.5h battery life). So a game that heavily loads the N7, can very quickly drain the battery.

Thank you for settling this problem with actual facts! IIRC the battery capacity was indeed 15Wh, though I didn't know max. usage was 5W, I thought it was more like 3-4W.
I'm a bit curious though as to how one monitors the system power consumption. Is ther an app for that?

I'm measuring via the USB port (I built a power monitor).
The N7 also has a battery gauge chip that can measure current. The driver logs some debug info, including a current drawn value every 60s. However, that value is only the average for one second, so it's not very stable.
In a root terminal, you can run
Code:
dmesg | grep bq27541
to get the debug info from the battery gauge chip.
(BTW, that current is the current flowing into or out of the battery, not the current used by the system.)

I use Battery Monitor Widget. Among many other graphs it provides a %/h graph. I can see in games my N7 drains at ~30%/h

Going from 0% brightness to 100% brightness adds another 1.05W (total of 6.05W = 2.5h battery life). So a game that heavily loads the N7, can very quickly drain the battery.

Great explanation. Thanks. What is then happening in Chrome? It's the 2nd biggest battery drainer for me. From what I can see it drains battery at the rate of 20-25% per hour.

Chrome is a CPU pig. Even sitting around on a web page with a single animated GIF will eat 1.8W at 0% brightness. Add in some web pages with a lot of Javascript (Javascript is extremely CPU inefficient) or not using an ad blocker (it's pretty common to to pull in ad-related Javascript junk from 20+ places on a single page and a lot of ads include animated crap) and you quickly get a lot more...
Does anyone know of a better battery that will work with the zl.
As we all know this phone really suffers from poor battery life and overheating. I've managed to solve the overheating problem by flashing miui v5 and have it undervolted @ 987mv @ 1512mhz with doomkernel and kernel tuner, the phone is very cool now compared to before. However battery life is still dissappointing lasting only 10 hours a day dropping 10% every hour with light/moderate usage. Onscreen time it will die within 3 hours
So I wanna open it up and put a better battery so I can use a different rom cos miui is very restricted imo. xposed framework doesnt really work well with it.

Stock firmware gives me 4,5 hour screentime MINIMUM! So its NOT as we all know. It's your phone and your apps. Mine lasts a good day with more then moderate/light use. 13 hours with 75% left at the moment and 1 hour 10 min. screentime. Wifi always on. When out of house, 4G/LTE always on. NFC constantly on. So its you. Not your phone.
22,5 hour on single charge. 4,5 hour screen time. 8% left. I can't see your problem.

Yes you are correct, Im using paranoid rom and battery life has improved a lot. I also found that heavy undervolting uses more battery life. I'm new to android so didn't know this. What roms are you guys using exactly?
battery life
So? is there any after market battery?
heres my battery life, can someone help me?
I get around 15 hours with the stock rom. I switched to existenz but i havent tested it yet.
And i really want to change the bat.
If there was a way to put a LiPo 3000mah in this thing...

You can buy new battery for xperial ZL from aliexpress.com. Not many vendors though, but its pretty cheap.
I ordered mine and it reached from China to India safely in around 1 month. Seems good and genuine, but have not tried it yet. As others have said, it may not be a problem with the battery at all and changing battery wont do any good. Check if its really a battery problem or not.

i also ordered one from ebay it says made in japan now its working smooth and giving me extra 3-4 hours of battery life
after three years of extensive usage, my battery has now reached the end if its life. It now dies at around 30%- 40%. I tried battery calibration but it works only once. after a full 100-0% run, the next run dies at the same 30- 40% level. I have been monitoring voltage via ampere app. when it reaches 30- 40 % range, the voltage drops significantly from 3.5 to 3.2 and below and shut off abruptly. also, now during heavy usage, battery temp goes up to 50 C.
Does this mean the battery is completely worn out? or something else may also be bad?
anybody else with 2-3 years of use notice the same?
and if the battery is at fault here, can someone suggest me a link where can i buy one?

Same here, phone shuts down around 40% and whats worse is that the battery has deformed and pushed motherboard up causing a lot of problems. My ZL USB port short circuited blowing smoke and now won't boot up at all. Tested the battery and got voltage around 2.8V, which means safety triggers won't let me charge it
