Battery Life Experience

The phone hasn't been out long enough for most people to have even conditioned their batteries, so any numbers you'll get in the next week or so are meaningless. It takes that long for a phone to settle down to something like normal.

It's a lithium ion battery, there should be no need to condition it the way consumers used to have to with Nickel based batteries.

A full discharge/charge cycle is useful every once in a while (maybe once or twice a year) to help the fuel gauge calibrate. They need it every once in a while as lithium batteries constantly degrade and calibrating helps the battery control circuit know the low charge and full charge markers as the battery degrades.

Thats what I thought, the days of cycling were over there is def something draining the batt. I am not a thousand BS apps kind of guy, I have couple of installed apps and that is it I might do a hard reset and and install no apps and try that for a day

Should the phone be fully charged before first use? Mine's due tomorrow morning, don't know if I should put it on charge during the day and play with it when I get home from work, or take it with me and spend all day "setting it up" :)

Any advice?
Im not tech. guru but I will say ive had a lot of phones recently and taken the right out and used them and never had a prob.

Did this with my One X and the battery was always shite - it was on about 40% when switched on in the shop when they set up the new sim card for me. At the moment I'm leaning towards leaving it charge for a few hours before I start giving it a hammering

My first day of use was unimpressive. It lost about 3-4% per hour when idle. The reason I call this unimpressive is that it doesn't differ from other Android phones I've utilized. (My Moto X, loses about 2% an hour when idle.)

Since then, I have let it discharge completely (or as much as it does before it shuts down), and fully recharged. Today will be the first day of use after that cycle. I'll post my results back later.

I got 20h on a charge you might say that is reasonable however about 15h was standby time with very minimal sunday use, looking at the battery log it was still discharging a little much even on the standby time I lost about 30% overnight wile sleeping witch was about 4 to 5 hours phone was not getting hot at all, Thank you for the input, I just did a reset on the phone and starting with a clean slate 100% stock im going for a full charge and see what happens. I had the same apps exactly installed on my s4 and when that would sit on standby it would flat line on the battery log so we will see .

Take the phone out of the box and use it to get it all set up. Then charge the phone up. If all of your prescribed techniques work then why hasn't HTC put those techniques in the user manual? If you had the M7 and purchased the M8 you'll see the difference in battery life. When you first get a phone and use it a lot the battery will drain. If you want the processor to idle slower, put it into power saver mode. If you don't have power saver mode, I feel bad for you but I don't think it's extremely necessary. Come on guys.

People say they don't notice a difference in speed with power saver mode enabled. I notice the difference. It's only a bit slower, but it's noticeable to me. Won't kill me to wait. These phones run so fast that they put my laptops to shame.

Also, I have a friend with a Note and he leaves the GPS on and mobile data on in our building at work. When he jumps in my truck he is hogging my charger. I'm like look, you wouldn't need to charge it every damn minute if you would turn your radio's off on your phone. In our building you can't get a GPS or mobile data signal because the walls are made of very thick cement. So why leave them on.

I remember a Sprint tech in the store telling me I should leave 3G always on. I was like I hope you are not telling people this because you don't know where they work or live. I know you can make the radio sleep after its not in use, but I prefer to keep mine off. I'll leave WiFi on all day if I'm near a WiFi network. But we don't have WiFi at work so my radio is off.

And you guys need to take into account some of the apps that need the GPS or mobile data like Maps. I turn location services off or it will fire up during the day to locate you for better location services. Google plus does the same thing so I disabled it and Google Music. If I don't use certain apps I disable them.

well I have everything set up totally stock, and use the hell out of my phone, web/phone/apps. First time droid owner ever, and I get a full day from 7am til I go to bed around 11 or so. I have yet to have to plug in because I was going to die.

I'm a droid virgin and have a few buddys that are somewhat savvy and have recommended some battery apps, although I'm waiting for the stock HTC extreme battery saver mode to be released.

So far, I'm happy with the battery life, use all day.. plug in at night.

Battery use depends heavily on the user and the way the user set the device up.

Signal strength, screen brightness, screen on time, etc are all factors that can impact this.

No 2 people are going to set the device up the same, nor will you get the same results as the next guy. Just the way it is.

If you find a trick someone can benefit from, cool, post it up. If you benefit from someone's advice, throw em a Thanks. :)

My battery has been pretty great so far. I'm currently sitting at 55% after 12 hours of pretty heavy use. I play on it a lot at work, and I have a 1.5 hour commute 2 times a day, in which I listen to books/music the entire time. This is with wifi/gps/bluetooth/nfc/gps on at all times and no power saving mode. I think I would have a pretty hard time to drain the phone in a day without playing too many games or watching videos.

Thanks for posting guys. Goes to show the M8 has raised the battery bar. When HTC updates the phone with Super Power Saver I wonder what their tweaks will consist of primarily? Can anyone explain?
The power saver basically turns off some functions of the phone. It turns data off when the screen is off, turns off vibrations, reduces screen brightness, and "conserves CPU power". On the last one, my guess is that it just downclocks itself, which should save quite a bit of power. All of this stuff can probably be done manually, but having it all in one option, and you can have it come on automatically at a certain battery percentage (I think), is really nice.

The Extreme Power Saver mode will make everything data related On Demand as well as use a simplified UI, kind of like Car Mode, to access only the most used things like phone and texts.

Edit: I just found this link

I know my M8 isn't defective. I noticed that my reception bars were stronger on my M7 and EVO 3D than on my M8. When I had my 3D deactivated in lieu of my M8 I noticed the difference. I wonder if it's possible that HTC has already implemented a piece of power saver? Why would I suggest that? Because the reception bars on my M8 may will show one or two bars before making a call. Once I hit the call button the reception bars increase in strength like flipping on a switch. I'll go from one to two bars to having five or six. From my understanding, CDMA networks in general are more taxing on a cell phone battery than a GSM network. Maybe HTC has figured out how to throttle back the reception until you actually need it, which in turn saves battery power.

The M8 shows LTE reception with the bars when connected to LTE (even if you are connected to WiFI). This is different from previous Sprint phones, in my experience, which did not show LTE signal strength via Bars. Test this: Check your bars while on LTE then switch from LTE/CDMA to CDMA only and watch your bars jump. Also when you are making a call you are switching to 2g so it is showing that strength (I think so anyway).

No difference in bars turning on 4G LTE. I'm on Sprint by the way. One of the knowledge tech guys from Sprint told me the reception bars do not indicate data signal strength, only voice reception/signal. I was asking him about Sprint Spark and he knew his stuff.

I'm glad HTC changed the icons in the status bar for 3G and LTE. Those were long overdue!

Are you sure? I am on Sprint as well and as I stated this is the first HTC Sprint phone to show LTE strength via bars. I am going to attach some screen shots so you can see what I mean. The first one is my LTE strength. I then switch to CDMA only and it shows my 3G strength. You may happen to be in a spot where LTE and 3G are around the same strength.

There is a huge difference in signal strength now because I went to CDMA only under mobile settings. So the phone reads LTE until making a phone call. That's interesting, which makes my earlier theory garbage.

Well I reset the phone to completly stock, let it sit untouched and still power was draining down was down mabe 8 to 10 % in a hour then i noticed i had missed a call they left a message and for some reason when I reset the phone I activated the visual voicemail trial, so I noticed the battery drop very quick so I decided to deactivate the trial and well all of sudden the battery stated holding a charge actually flatlining, if anyone has info on that app please share .
