Why is my HTC M9 draining fast?

[AC Question]

htc m9 week old and drains fast

I had this phone for a week now and This is my usage for the past three days. THe first day I was downloading a few apps and it took some time which drained my battery around 5 pm. So I gave the download an excuse. it finished charging around 12 pm due to a faulty charger but that is not the case. Since 12 pm till around 11:30 am of the nexxt day the percentage dropped from 100% to 77% and from 77% to 0 around 9:30 pm. The usage I did was download two games about a 2 gigs total and then wifi usage total 15 mins of web browsing and for the rest of the day. Today, I decided to leave the wifi off till I wake up. So I charged it and finished charging at 1:16 am yesterday, and woke up around 5:30 am the charge went down from 100% to 93%. Well with the wifi off. and then I used it again around 6:00 am for 20 mins and the charge went from 93% to 88%. and I slept.Then, I woke up 11:00am and it went from 88% to 78% with the wifi off. When I look at the battery usage says some programs uses it like instagram which I barely open,facebook and its messenger. Is it related to the processor? which makes it a power hog? or a software issue also? Any way to make the battery last a bit long? Should I just keep it on power saving? forever?

What you're going to hear is post screenshots for your usage. Your times don't seem right some how, but I will say I have the M9 and since this last update I get better longer battery life when connected to Wi-Fi. It showed I could go today's on my charge on a Saturday when I never left the house. Sunday when I was out all day I barely made it home around 6. Is this normal? It's all subjective and everyone use different stuff and moss thru different network activity. The last portion you described sounds like my normal day. Right now I haven't left for work and I've been on and unplugging for an hour and twenty minutes and I'm only down 10% but when I get to work I'll lose that much in less than half that time probably far less if play a game or two.

Sleuthing a little here. You mention having the phone a week and then describe three days of power usage. Had the battery lasted longer the previous 4 days (and if so, what did you download)?

My experience with this phone has been battery drains have always had a source, my VPN software, a ridiculously weak Sprint LTE signal, apps trying to keep me up to date about something unimportant.

Maybe disasble your mobile data for an hour or two. Maybe the draining will stop and you can narrow down the suspects.

Re: htc m9 week old and drains fast

Ive just solved my Battery Drain isue.. It was "Android System Webview". I disabled it in Apps.. and my M9 is running lovely again..

Im using a UK Factory Unlocked M9 on v2.10 (yours may be different according to your region).

Webview does come with security fixes and updates from Google and allows you to View pages and use content from different apps and the web all within the Chrome browser as well as being a test environment for developers, so it can be useful.. Just be aware of that before you disable it.
