Day 6 of my 4g slide and today I got (on the stock battery):

11:37 minutes before it wont power on.

I'm coming from a g2 and I'm not doing or using anything different.

I am assuming that sense is a power hog and that once we have ASOP roms our battery life will increase. I am, however, going to buy a 1900mAh battery friday.

Less than 12 hours of 4 minutes of phone calls and moderate texting is pretty pathetic, and I'm on wifi most of the time too with my screen brightness set to 20%.

Comparison: from 8am til 5pm of the same use, my g2 was at 70%. This phone is down to 16%.

Don't crucify me, I am draining and recharging the battery to calibrate it and will update after a week. I am simply posting my first few days right now.
[T-Mobile myTouch 4G Slide] icoman:
I got one of the new Anker batteries today (1900mhz). Even on it's first use I can tell this battery lasts much longer than the factory battery I'm 6 hours in and I still have around 75% left after moderate of use Wifi calling, Wifi internet surfing, a few games, etc. :p So I'm expecting this battery to last much longer after it's calibrated. It should easily get me through a full day (10-12hrs) now no matter what I do with it and I expect I could stretch 24 hours out of it.

A strong word of caution though, there is a disclaimer on the package that states that disassembling, or crushing the battery could increase the risk of fire and/or Bums.

I guess bums love phone batteries in China.
[T-Mobile myTouch 4G Slide] jonathan3579:
In my experience with this phone, WiFi kills it unlike many other phones I've used in the past. Having both the Sensation and this phone on WiFi always shows this phone draining at a much higher rate.
[T-Mobile myTouch 4G Slide] Blue6IX:
So is the battery you got the one stating compatibility with the HTC Sensation?

Amazon links to This, This or This should work - is this the same battery you got?

(link goes to the same battery, 3 different deals though posted for others in case it's the right one)
[T-Mobile myTouch 4G Slide] token2k6:
haha, yeah what is a good link for this Anker's battery? This phone hits my doorstep tomorrow, couldn't be more excited, now I'm trying to find everything else for it before I run out of money :p already know the zagg is the first purchase..
[T-Mobile myTouch 4G Slide] Madblaster6:
This is my first charge since I bought it yesterday and I got 20 hours and the phone is currently on 1%. I have location services on but gps, wifi, and bluetooth off.
[T-Mobile myTouch 4G Slide] Kaczman:
is that the correct battery?
[T-Mobile myTouch 4G Slide] ratchetrizzo:
Update:

Yesterday I got 16 hours before 0

Today I got 12.5

I;m ordering a 1900mAh replacement friday but I expect the stock battery to level out around 16-18 after a few more days of conditioning
[T-Mobile myTouch 4G Slide] itsomaryo:
To all wondering yes the sensation battery fits in the 4g Slide and the battery is amazing!! (I have the sensation and my mum has the Slide)
[T-Mobile myTouch 4G Slide] icoman:
Yes itsomaryo is correct its the same as the sensation battery.

And yeah looks like its the screen and wifi that hits me the most. Things like dlna streaming also run it down.

I got 24 hours from the anker but a good 12 to 15 hours of that was standby. I'm still pleased with it. Did a few hours of talking and some texting, ran dlna and bluetooth a while, played a few games, surfed the net, other junk and it lasted a long time. Really good battery life for its first use considering it was under $20. I think it was like $14.
[T-Mobile myTouch 4G Slide] cberbes:
I see the 1900m batteries, but I am also seeing 2300m batteries for the HTC Sensation. Would those work?

THIS ONE
[T-Mobile myTouch 4G Slide] napilopez:
Given that the 4G slide and the sensation use the same battery, it should, but I am slightly wary because that seller does not completely specify that it is the exact same size as the original battery. I don't have the sensation, so I cannot be sure, but if the battery is just a little bit larger there's a chance it might still fit in the Sensation but not in the MT4GS.

EDIT: Reading some reports from Sensation threads, I'd be wary of these 2300 mah batteries. Anker at least seems to be a more trusted name.

As for my battery life, the first day was quite bad, the second was a bit better, but today I got through a full day with a whole lot of texting browsing, GPSing, app installing and actually more intense usage than my usual. I'd say about 16 hours as well before it dropped to 10%. I think my experience further solidifies that there is some sort of power leakage going on with WiFi. Those first two days I spent mostly at home with Wi-Fi on(and mobile network off), but today I was out and about almost the entire day, with autosync on for all of it, and used it alot more than I did in either of those two days yet still got through the day without needing a recharge. Granted, the battery is still calibrating, but I was very surprised. I will probably still order a larger battery though, for the sake of security.
[T-Mobile myTouch 4G Slide] cberbes:
Well, I think I figured out MY problem. The one thing I never turned off on any of my Android phones, rooted or not, was "sync background data". I only turned wifi on when I was going to download a larger file or was getting poor 4g reception in my house....I almost never turned on BT, and I have my account sync off. But as I have mentioned, I have been getting horrible battery life.

Today I turned off "background data", and with heavy use I still have more than half my battery life left. Based on how the battery has drained since day 1 and the useage during those days, I would have had a dead battery by noon today. But at 6pm I still have more than 50%. So in my case, it was turning off background data.
[T-Mobile myTouch 4G Slide] napilopez:
Hmm, one thing I noticed with mine... I got a pretty bad day even with autosync off the other night, but yesterday I was thinking and realized the Main clock weather widget refreshes everytime you view it even if you have sync off. I took off that widget, only leaving the large, full screen weather widget in another panel which does manually refresh, and my battery life seems *substantially* better. Again, I'm not totally sure because of battery breaking-in issues and such, but it does make some sense, seeing as the clockweather widget always refreshed.
[T-Mobile myTouch 4G Slide] tt2by2:
Has anyone used a GTmax battery from Newegg?

newegg.com/Product/Product.aspx?Item=9SIA07Y03D6320

can't post a link because of post count
[T-Mobile myTouch 4G Slide] AviatorJud:
Just received the Anker battery from the ebay listing that said it was for the MT4GS, but the one I received is labeled for the Sensation. I understand the battery is the same model, so no big deal. However, as I've noticed almost every time I buy a non-OEM battery, its dimensions are very slightly off. The Anker is slightly thicker, which is ok because the batt cover still snaps on all the way(barely). But what concerned me more was that it was a VERY tight fit lengthwise inside the battery compartment. It's in there, but it's so tight that it is somewhat difficult to remove with a finger nail. Just a little worried about the stress it is putting on the phone's structure, as well as the contact pins. Anyone else notice that the battery is slightly oversized?
[T-Mobile myTouch 4G Slide] sonicjam:
Well guys I'm going to put my 2 cents in here. I've noticed a huge battery life difference when turning off my phone's data connection. I have bg data checked on, auto sync on, and power efficiency off. Today before I leave work I always have my phone fully charged. With data connection off I go to work for 8 hours while between those hours i have two 15 min. breaks and a lunch break. There is were I turn on my data connection to check facebook, g+, and XDA. As well calling my GF. At the end of work my battery life was in the 80s percentage.
[T-Mobile myTouch 4G Slide] AviatorJud:
Yes, and if you never use the phone's screen you'll save even more power. But as someone else said, that's like buying a car and never driving it. For me, I need quick access to data all day long. After all, I bought this device because it is a pocket computer. If I just needed a phone, I'd have the cheapest flip phone.
[T-Mobile myTouch 4G Slide] AviatorJud:
One more thing I just noticed with this new battery is that the temperature reading is completely inaccurate. Knowing how hot the stock battery got when charging, and feeling the back of the phone, I know the battery is actually in the 90's F, but the temp is only showing 75F. Not a huge deal I guess.
[T-Mobile myTouch 4G Slide] sonicjam:
Yeah but I'm at work and I can't use my phone. When I'm home or out I'm on it heavily.
[T-Mobile myTouch 4G Slide] AviatorJud:
I understand. I'm just pointing out that not using the device isn't the answer to getting better battery life.
[T-Mobile myTouch 4G Slide] _atlien_:
Two suggestions:

1) Get the battery made by Anker. It says it's for the Sensation but it works for us. And it's 1900mAh instead of the 1520mAh that comes with the MT4GS.

2) Fully charge the battery before you use it. Then let it run down all the way through usage. Til the phone turns off on its own. Then fully recharge again.

I'm getting over a day and I text A LOT. Take about 40 photos a day and a little video here and there. Upload a lot to social network sites. And talk for about 45-60minutes daily.

The battery plus charger is $11 or $12 on Amazon. Anker.
[T-Mobile myTouch 4G Slide] Kaczman:
Agreed. Ive had the anker battery for 5+ days, and my battery life is nothing short of astounding. Under moderate usage, all day long, wifi, gps, calling, texting, facebook: I have 30% left after 16+ hours. This battery is AMAZING; probably the best $15 I've ever spent on any cell phone item.
[T-Mobile myTouch 4G Slide] cberbes:
Today was the first day of normal usage since root and removing a lot of bloatware apps. Best day yet. Played Angry Birds alot, normal amount of texting, and slightly more internet. Unplugged at 7am, still have more than 50% battery at 9pm.

Based on my usage, prior to root and leaving sync background data on, I would be dead by now. With background use turned off I would be around 25%. But with root, background data, BT, WiFi, and GPS off...but leaving data on I am over 50%.

I removed facebook, youtube, telnav, carbon backup, that video chat program, and a bunch of other stuff. I also uninstalled the preloaded notepad app and installed Color Note, because I noticed the preloaded one was always running. I'm going to uninstall MAPS and reinstall it because I can't seem to get it to stop either. But nonetheless, since deleting all those apps, by battery life is back to solid levels like my rooted CM7 G2.
[T-Mobile myTouch 4G Slide] napilopez:
I just got the Anker battery today. EVERYONE GET IT. Seriously. I'm not exactly sure how they fit an extra 380 mah in there, but they definitely did it. I'm guessing the HTC battery has some unused space, because I didn't need to pull out a scale to tell the Anker battery is heavier, and you can see it's about a millimeter thicker(its a lot of a tighter fit)

The battery isn't even fully calibrated yet but when I got the package, I put it in my phone at about 4:50, when it had about 50% available. It's now 12:12 AM and the phone is at 13%. This is using my phone a good deal more than average too, purposefully trying to drain it. Was texting constantly, and spent at least 2 full hours of that time web browsing. Even more tellingly, I enabled autosync, which I normally have off, in order to drain he battery more quickly. Powersaver doesn't come in till 10% on my phone. I purposefully left Wi-Fi on the entire time yet was never actually connected to a network, using my 4G connection the entire time. Add to this that I didn't spend time micromanaging things like brightness and running applications as usual, and it's clear this battery is a winner. I can finally leave my house for a long day without worrying about needing to bring a charger with me!

As someone else said, easily the best 14 dollars I've ever spent on a single phone-related purchase. I wish HTC had included such a battery themselves. It does seem there's some sort of energy-usage leakage going on, which I hope HTC addresses in an update.
[T-Mobile myTouch 4G Slide] cberbes:
Ok, deleted the preinstalled note pad app and installed Color Note, which never runs in the background. The strange one was Maps. I could never get Maps to stop running in the background. I would force close it and it would start running again in moments. So just to try it, I uninstalled it using TB, then went to the market and installed Maps again. Now it never runs in the background. Not sure why, but it works.

Today I used the hell out of my phone, a lot of internet, following the WM3 case, so I was pretty much online from 9am until after noon, played a lot of Angry Birds, and sent and received many texts, and a bunch of pic messages. As it stands right now, my phone and my Wife's MTS4G (unrooted, but same settings as I had) have the same exact battery life left, and she didn't use her phone outside of the texting we were doing. No internet, no Angry Birds. Same battery, easily used mine twice as much.
[T-Mobile myTouch 4G Slide] AviatorJud:
I have confirmed that my Anker battery's temperature sensor does not work. It reports nothing outside of 75-77F over a wide range of environments. My HTC one was getting up over 100F during the days when I was outside and sometimes when charging.

Just wondering if they're all like this or just mine.
[T-Mobile myTouch 4G Slide] _atlien_:
I'm curious as to whether or not the 10 hour battery experience is linked to having constant sync on. If your syncing constantly your battery will disappear. I don't sync. I check my gmail/facebook/tumblr/twitter when I want to. When I don't want them, they aren't doing anything. My battery lasts at least 24 hours between charges. And I take 40 photos or so a day. I recommend folks turn off the sync tool and do it yourself when you need to. And I don't use any task managers.
[T-Mobile myTouch 4G Slide] ekoee:
Getting a constant 12 hour-ish battery life. Everything turned off (auto sync, bluetooth, wifi unless somewhere with good wifi, gps) and mobile networks off unless I'm using the internet. I make sure to sync all once a day, usually when I'm charging.

This is with constant texting, moderate browsing and playing games. I don't think it's too bad, but then again I do bring my charger around just in case it dies.
[T-Mobile myTouch 4G Slide] mat_oli:
I bought the Anker 1900mAh battery, and yesterday, I went from 100% to 35% after only about 10 hrs...but I think it mighta been because I had K9 mail set up to poll every 30 mins..? I turned off the polling for today, gonna see how the battery life is without that.
[T-Mobile myTouch 4G Slide] RazoE:
I have one of those Anker batteries, and it works great. A free app I recommend is called 2x battery, what it does is cuts your mobile data (4g, 3g, etc), while the screen is off, but you can still receive calls, texts, ect.

This weekend, combined with my Anker battery, I got about 25 hours of use (with 19% left), including shooting 1080p video, and a couple pics at full 8mp..

Also for those complaining about how a more powerful phone should have better battery life and comparing it to cars have the idea wrong.

Less powerful cars (or phones) use less gas (aka, battery)

More powerful cars (or phones) use more gas (aka battery)

There's a reason a Toyota Corolla gets 32 miles per gallon, and a Lamborghini Murcielago gets 9, just look at the power differences!
[T-Mobile myTouch 4G Slide] neanderthal0:
Should have did some reasearch on dual core phones before buying one. During constant use I also see about six hours and with out use about telweve before death.
[T-Mobile myTouch 4G Slide] ekoee:
don't flush it down the toilet, send it to CM or Virtuous pl0x.

nah in all seriousness though, take it back to the store and tell them the battery doesn't last as long as you expected, only a whopping 6 hours. they'll probably replace it for you.
[T-Mobile myTouch 4G Slide] napilopez:
There's definitely a software thing going on. With the Anker battery, I find myself unable to drain the battery in less than 16 hours. I just can't do it. Just yesterday I unplugged my phone from the charger at 11:30AM, used it moderately all day until 12 AM, and the battery didn't even go below 60% until about 11:50. It's been at least a week since I last saw yellow on the battery meter, and I use my phone alot. A couple of videos watched, some calls made, a lot of pictures, a whole lot of texting, and even more web browing. Background data and always on data both activated, wifi on half the time, some GPSing. During Hurricane Irene I was using the stock battery so that I'd have the anker as a backup should power go out, and it still lasted me the day with alot of browsing.

I think I'm going to start a battery saving thread because although I'm not sure what change(s) caused the battery to improve so much from a very lackluster start, I'm pretty sure some of them had to do with it, and I'd like to help others improve it. I rooted my phone, froze a bunch of unecessary apps, and since then I've been rolling. The only battery saving features I use are having autosync off and automatic brightness off(although I have the latter turned on at the moment for testing purposes). According to the battery use settings page, at the moment the phone has 6 hours and 40 minutes on battery and I just hit 70% now. 65 percent display, the rest other stuff.
[T-Mobile myTouch 4G Slide] mat_oli:
yeah, please do share what apps you froze..I also bought the Anker battery, have Auto sync off, and auto brightness off (altho my screen brightness is set to the highest, so that could be killing a lot of battery), but from 8am in the morning when I leave the house at 100%, I get home at 6ish, and I'm down to 60% easily...and this is with nowhere near the kind of usage you mention.

I'm wondering if it's because my 3G signal drops in and out while I'm at work since I'm on a pretty high floor of the building, so it takes a lot of battery to keep trying to connect..?
[T-Mobile myTouch 4G Slide] napilopez:
Well, losing 40% in 8 hours is completely respectable, unless there's something I'm misunderstanding? That implies somewhere around a 20 hour battery life before you battery actually gives away. What was your usage like?

Still, this phone has a lot of bloatware.

I've frozen Tmobile Backup

all the sense widgets,

Video Chat(I use skype if I'm going to video chat anyway),

Calendar(Always seemed to be running TWO processes, again for like no reason),

DoubleshotAndroidZipgroups,

HTC Media Uploader(I saw this running a couple of times).

Now obviously not all of those have anything to do at all with battery life, and not all of them did I see running. Still, freezing some 50 or so apks I don't need has to yield some results right?

As for my other system changes I can think of, for a while I didn't have any weather widget though now I'm using GoWeather to no noticeable adverse effects. I usually have autobrightness off, although today I'm trying things with it on. My brightness is usually about 40%, or whatever the second brightness setting on the power control widget is. I use the lowest brightness when I'm in completely dark room at night, and use the highest brightness when I go outside. I turn off wifi when I go out(if I remember), have the GPS off unless I need it(which Ive used about every other day for a hour or so).

Currently Running services:

Settings

Go Weather

Go Launcher EX

Go Launcher EX Notifications

The Weather Channel,

(Google) Music

GO SMS Pro

Dragon Dictation

Slacker

HTC Location service(I'm about to freeze this one, just read it only affects HTC apps and widgets, which I don't use)

Visual Voicemail

Google Services

Maps

Swiftkey X

Right now I'm at about 65% with 9 hours and a half of being off the battery. That yields in about a 27 hour battery life total, assuming a relatively linear dropoff, which seems to be consistent with my results. It would probably last longer given than Ill be going to bed soon.
[T-Mobile myTouch 4G Slide] mat_oli:
Thanks for the list, I'm definitely gonna try freezing out some of those apps too...I was just really surprised when you said you had been basically running for 12 hrs before dropping to below 60% using the phone moderately..

For me, losing 40% in 8hrs was pretty surprising considering how little I was using the phone (all I was basically doing was checking the occasional email, no web surfing, no picture taking, no gaming at all), which is why when you stated your battery life I really wanted to know how you were achieving that..but I'll definitely give your list a try...
[T-Mobile myTouch 4G Slide] napilopez:
Oh yea then definitely give it a try. If you were only emailing and such there's no reason it should have dropped that fast... particularly since you already have the Anker battery. Today has been a pretty light usage day for me: I've been outdoors and thus have only been texting, making a couple of phone calls, and doing a little browsing. My usage today seems comparable to what you said was your usage. Yet I'm 5 hours off the charger and the phone is currently at 91%. You should be getting better battery life.

One thing I forgot to mention is that I wiped my battery stats as soon as I installed Clockwork Recovery in order to delete the default battery stats and make new ones for the Anker, so that might've contributed as well.
[T-Mobile myTouch 4G Slide] mat_oli:
hmm looks like I have a lot more stuff running than you, that's probably why..here's my list, after a reboot of the phone (and before I start running anything):

[T-Mobile myTouch 4G Slide] aanarchyy:
I went and purchased the 1900mah Anker battery and if anything i would say it is worse, but maybe i just need to wait for it to settle first. I calibrated the battery as soon as i got it and charged it and its gone through probably three full drain cycles so far.

One thing that kinda concerns me is that the phone still reports that the battery is only 1580mah, is that normal or do i need to fix some setting or something?
