So, I've had my sensation for a week, it was nearly perfect. But I wasn't sure that it was the best unit, cause battery was used fairly quick, GPS kinda weak, and a slightly washed out screen. I took the 14 day advantage I had at Walmart, and just today headed out there after work to grab the last unit they had! I called like 5 diff. walmarts but only that one had one unit.
Even the box was in such pristine condition, compared to the one I bought earlier, even though both were new. The first box had a date of 5/27. This new one has 6/3, so I'm hoping the June units might be better. Both Taiwanese. I haven't even opened my new Sensation yet, feel excited all over again
Anyways, to come to the point, how did you all start using you new phone, did you just take it out, turn it on, and use it? Or kept it off, charged it all the way, then use it? The reason I'm asking is cause the first one I had, I kept it off and charged it all the way. During that process, the phone got extremely hot towards the bottom, I mean hot like I've never ever seen in any phone before. And it pretty much stayed that way for atleast 2 hours straight. I'm thinking that I maybe messed up the battery up, cause too much heat can damage them. What do you guys think?
Edit: Another thing on my previous phone: the battery gauge was wacky. I would use if for hours and it would stay at 100. Then suddenly show like 85 or something.
usually I will leave it off and charge it fully before using it. This time I turned it on right away, let it drain then charged it fully while off. I've only had my sensation less than a week so really cant ccomment on battery life. When you first get a phone though battery life will be worse because you play with it tons when you first get it
Charged it before turning on & it never got hot
Yeah, mines seemed like a fluke, I've never had a phone do that before. This time, I'm thinking that I'll prolly turn it on before charging just to be safe.
My first two, I did. This one I used right away and today it's been unplugged for 11 hours and I'm still at 47%
I play with it until it fully dies, then I let it charge all the way; for the batteries sake. It last much longer that way.
I couldn't wait for it to charge completely.
I wasnt even out of the T-Mobile parking lot before I had my sim card in it and was messing with it lol.
Could you please tell us how your new phone is? I'll update my post when I check my box for the date but my battery does heat up and my power button is the slanted one.

Exactly....that's what most all manufactures recommend. I didn't notice it in the Sensation's manual, but I know I saw it in my G2X's manual.
For the last 5-6 devices I've had, I always run it dead from the box, then let it fully charge to 100%. As far as I can tell that really does help either calibrate the driver or condition the battery. I also do that pretty much every time its convenient.
I've never just charged it straight from the box.
I've always had great great battery life, under heavy use, for every phone I've had using that method.
I really don't know how important it is, but I know I've never had any of the battery issues that it seems many have with various devices.

Great advice, however I wanted to ask you that when you charged it back to 100% the first time, did you keep the phone off all the way? Also, did you perform any kind of a hard reset on it, and if you did, at what point?

I will surely report that info as well as panel info tomorrow after 7PM, as its late, and I havent opened the box yet. I was still trying to figure out the best way to start using the phone, as I didnt want to repeat the mistake I made last time.

No, I let it die...plug it back in, turn it on.
Some people do factory resets out of the box....I never have (out of the box)...
I get easily a full day, 14-16 hours, with consistent use. WiFi always on, gps on when needed, tons of web activity, light gaming, 100+ texts, dozen or so calls. That's pretty normal.
The Sensation seems to go from full to 90% in a hurry, but then really levels off. No idea why, but it's undeniable with mine. Also, this phone is by far the best I've ever owned when it comes to idle power consumption. I'll regularly leave it unplugged while asleep and it might go down 5% at most.
That's my experience.....hope it helps.
Hoggles, thx so much for your insight. So after reading quite a few pages on other forums, especially the IPhone ones, I think I'm gonna fire it up and drain it & then charge it fully while its off. Now the only thing to figure out is when to factory reset the phone, as soon as I first turn it on, or after it has fully charged? Also, when fully charged, is it best to unplug it and then start it, or start phone while plugged in, and then remove the power cable once it comes up?

I really don't think ya have to get that nit picky...as far as when or how to unplug.
Pretty simple and hard to go wrong....
Out of the box....use it til it shuts off on its own
Plug it in....
Turn it on if ya need to receive calls etc...
Let it charge to 100%...
You're Golden
Repeat whenever you have the time...once, twice a month works for me.

If somebody helped here, go back and hit the thanks button. It's a small gesture, but it lets the poster know you really liked it
I'm also use it out of the box until its battery drain and warning indication come out. Then I charge my battery.
I facing a weird condition during charging, where its goes up to 80 or 90% fast, but then to reach 100% very slow. It took 3.5 to 4 hours for my phone to reach 100%!!. I already use my phone for 15 days.

This is the "proper" way to condition a Li-Ion Battery. it's best for the battery life during every day use and into the long term. Ideally you should use it until it get's down to about 2-3% then charge fully, and repeat at least 2-3 more times. Your battery will thank you for it.
I had started to think that this tried and true method was NOT working on my sensation and then today, almost one week precisely after I'd gotten it I saw a huge, noticeable difference in battery life over the first 3-4 days.
Condition your batteries people! You and your phones will thank you for it!
I got the phone at Walmart the first day it came out and used it then charged it all the way.
Phone got very hot and I can not get it to last more than 6hrs on a charge no matter what I try.
(No GPS No WiFi No extra apps......you get the point)
Trying to return the phone to Walmart but they don't have any.
Something is definitely off her but I don't know if it's the phone or the battery.
Ok, so I have my Sensation XE since februrary never experienced battery issues since, except in the past these days. I usually recharge my phone once every 2 days, but now I am *forced* to recharge it every day right before going to sleep.
I don't know what to say excepting giving you some situations. I fully charged my phone saturday at around 5-6 PM. Next day at around 5 PM my battery went to a little under 15%. My phone usage was minimal (only 45 minutes of display), i don't really talk much on the phone, I don't remember how many minutes I spent on phone calling during that time, but I know it was around 10-15 minutes MAX.
Now more recently... i fully charged my phone on the following day (sunday, yesterday) at around 11 PM. Now it's 7 PM, Monday and i'm sitting on 14% 2h27m display time (in 20h30m since discharging from 100%). I usually get a time of 1d10h with 2 hours of display on, but now I'm struggling to get more than 24 hours.
I'm really considering replacing my battery with a better one (not the OEM standard one).
PS: I haven't changed my usage habits, I haven't installed anything that could drain my battery (besides, I always follow the "Awake" bar on the battery history details, and it's ok), I'm using stock ROM.
Try rooting and install different ROM. See if it helps. If not then maybe its time to get a new battery. Btw Anker 1900 mah battery is cheap and works very well. I bought some time back and really happy with this.

No. I want to keep it stock.
If you're going to get a new battery, I'd advise you to get an Anker.
I'd try another battery then if you want to keep stock not much can be done in the way of tweaking. I highly recommend a extended battery. Anker is a good one. If you want an even bigger battery try mugen. Most are very happy with Anker.its inexpensive and works well..best of luck.

I've solved my problem, the battery is fine. I removed Google+ (or at least the data associated with it).

Noticing your Galaxy S6 battery is draining too fast? This thread can help.
Part of the problem lies within a memory leak which is a known problem that Samsung is aware of and is reportedly patching in an upcoming update.
The other issue is Samsung attempts to load everything into memory and run several services in the background as well as hard loading the phone with bloatware.
Here is how I gained 30% better battery performance. Guaranteed
*Prerequisites
*Need to be rooted for every tip to work.
1. Disable anything you consider bloatware
2. Go to settings then application manager and disable both ANT radio service apps. You don't need this. Causes massive battery drain. Google it if you don't believe me.
3. Go to the app store and download "Servicely" from Franco. Paid app but worth the money...trust me. (Need root)
4. Once in servicely add running services and apps to your hit list, choose start at boot and run hit list while screen is off.
5. Reboot your phone. Give your phone a full charge and see the difference
Attached is a screenshot of realistic usage. I was on a poor lte signal for 9 hours and conducted several calls and used my phone moderately heavy. As you can see i got through my entire work day and still have 6 hours left at moderately heavy use.
Remember, this is realistic. I could have shown you a screenshot showing 18 hours left after only using it 1 hour. What I'm showing is a legit 9 hours of usage. Before I made these tweaks I would be at 10% battery or less after nine hours of the same usage.
Post your screenshots after 24-48 hours and let's see how much you are saving.

Do you have a VZW Galaxy S6?? or are you using a TMobile one?
Without doing most of what you have on the list:
Didn't load Servicely
Did not turning off ANT which is a low power service used by heart monitors and other physical monitors
Did already disabled the apps I don't use and
did the deal with the google services/play but not much other than that.
I don't play games on my phone, but I do use it for business, calls, lots of messaging and keep WiFi on most of the time except when I am between locations when I turn it off. I only use BT when driving and keep it off normally.
All of which can be done without root, though I have rooted my phone.
YMMV but a lot has to do with what apps you do use, what you actually turn off etc...

Yes I have VZW. Use your phone for a few days and you will start to see battery drain due to the memory leak primarily and your load of apps

I've had my phone for 10 days now. Rooted the first day, loaded my apps and configured that day and sunday so it was work ready on Monday. Ported my number over Monday morning. Pretty much the same for the past 7 days now since then.

Its kind of like who cares?
There are 24 hours in a day and I sleep at least 7 hours of that. The screen shot shows it is 6 in the evening, the phone has been on for just under 11 hours and it still 53% full with an estimated 12 hours left. Even if I am up for say another 5 hours or so, I will still have another 4-5 hours worth of power easily and since I sleep with my phone on a charger every night I won't run out.
On top of that I have AC powered chargers all over the place, in my home office, by my recliner in the living room, in my office at work and even in my truck where I have a two port USB charger with 2A each which is better than some AC chargers. That is in case I really start using battery power for some reason and need to recharge sooner than once a day. All of which was purchased when I had my Note 3.
The costs to get into this phone has been one of the lowest of any phone I have ever purchased since it uses the same chargers, same apps etc. The only thing I bought was a light case as it is slippery without one and I picked up a $12.88 QI charger to use at work.
The phone already gets better battery usage than my previous Note 3 with a larger battery in it.
Stand by drain is high.... s not really relevant.

Let's stay on original topic and let's share ideas and be kind to one another. No need to be adversarial. Let's just offer up some cool tips.
anyone else notice it? first off, I'd be at like 40 minutes screen on time before I'd drop to 99 percent... now, it drops immediately after unplugging, and that 40 min screen on time, I'll be at like 69 percent now. it's absolutely ridiculous. battery drains like crazy now, but nothing is running in the background that shouldn't be. everything is identical to pre 8.1 update. today I was at right under 60 min screen on time, at like 59 percent. I looked at old screenshots pre 8.1, and I'd be at like 2.5 hours screen on time at 59 percent. it's absolutely ridiculous that Google is purposely ruining the phone with each update in terms of battery life. I'm not the only one, either. it's on reddit as well. planned obsolescence? yep, I'm starting to think so.

Man. Do you live off grid or something and can only charge every 2 days or something. If you want 3+ hours of SOT than you would have to be close to a charger anyways and that's with any phone. All these phones that have come out late 2016 early 2017 have the same battery set up...use your phone and charge it fast and use your phone some more.
My pixel 2 same as my Moto z2 force and my s8

I really doubt it's any different than it was. It's more likely the battery wasn't reporting correctly in 8.0. When I was on 8.0 the battery would sit at 100% for at least an hour, maybe 2, all the while I was using the phone. Yes, since 8.1 it drops much faster when I first start using it after removing it from the charger but at the end of the day I still have pretty much the same battery percentage left as I did when I was on 8.0. It drops faster to begin with but in the end, it's the same as before. Rather than planned obsolescence, it's more likely they simply fixed something that wasn't working properly before. There's no way you can use one of these things for an hour or more and not have the battery drop below 100%. Just my two cents worth.
Can't complain. Forgot twice to plug it in at night, woke up both times with 45% left. At my regular use that is good. My previous S7 would have been down to <20%. BTW, this:

is just utter BS, maybe you should reinforce you aluminum hat...
I can't say my battery life has been bad or gotten worse with 8.1. If anything it got better. I didn't plug mine in last night, woke up with 38% left. That was about 20 hours since last charge. I don't think Google is purposely obsoleting their newest phones a couple months after release either.....
Edit: I should mention, I have my AOD always on, I have Now Playing enabled, double-tap-to wake is disabled, and I use one of the prepackaged Pixel 2 live wallpapers (Marvelous Marble). The only ting I really do thinking of the battery is turn the phone face down when I go to bed since that shuts off the display.
so i guess the fact that my screen on time has dropped by over an hour means I'm the one who's crazy, and the phone is perfectly fine.... riiiiiggghht.

I'm pretty sure this part of your post is the crazy part. Your battery drain is probably real. Have you confirmed it exists on a clean install without any apps installed or system configurations changed? Only then should you entertain that this is Google's fault. Even then, accusing them of doing it on purpose runs dangerously close to tinfoil hat territory.
I feel my battery life has gone down slightly going from 8.0 to 8.1. Though, I'm running all the bells and whistles this phone has to offer, along with tasker profiles. I also agree with the previous statement. Perhaps the system wasn't accurately measuring the battery life.
I did have horrible battery life for a bit when I was playing with a new kernel and dirty flashing some things to get Viper4Android working.
I have two Pixel 2 phones (non XL), and honestly they are amazing at battery compared to my HTC M8s (again two) . Are they perfect? No. Are they better than any phone I've ever had? Yes.

As has been said above, the battery no longer sticks at 100% for the first hour or so of screen on time, but that was always obviously nonsense anyway so a fair conclusion is that it's now better calibrated. But I've noticed no difference overall in battery life: yesterday was the first time I tried running for 2 days rather than charging overnight, and when I plugged it at night it had run for 41 hours with 6 and a quarter hours screen on and 7% remaining, so really not a problem there.
If you're having trouble with an update:
- Use BetterBatteryStats to figure out if any apps are acting up (or just top off the battery, use phone normally, and check Google's battery stats for Apps Using Battery, standby drain and screen on time)
- Clean flash the factory image, set up phone as new, go through charge cycle and check stats.
I'm not having any issues with battery on 8.1 (clean installed factory image). Easily get 4 - 6 hours SOT. As a matter of fact, my battery life is shockingly excellent for a smaller device like this.
Google is not making battery worse on purpose with their brand new flagship device.
I don't have any issues with the battery after the 8.1 update. It doesn't stay on 100% for a long time like it used to, but like everyone else is saying, that must have been buggy before. It isn't realistic for the battery to stick on 100% with 40 mins of SOT. Overall I don't see a reduction in battery life and I'm quite happy with the 8.1 update.
I was checking BBS and couldn't tell much. Do you still need to install it as a system app?

Not sure. I haven't used it for quite a while. The built in battery info works well enough for me, I haven't been having issues. It's good for checking wakelocks and some more advanced stuff but I think it needs a few cycles/days before it can analyze properly.
I think it's just the way oreo is. Ever since 8.0 it just drains the battery very aggressively. 8.1 the OS runs smoother, but battery drain is still high. Been the case though since 8.0 for me, nothing new.
I haven't clean flashed in over 6 months though. Just been on 7.1 and been rolling up the OTAs and chugging along. I found using Naptime by Franco helps a bit.

IMO battery life has never been great on the Pixel 2. It's the same on 8.1 as it was on 8.0 for me.
Right now I'm trending towards 6 hours SOT (3 hrs SOT at 50%), and I have been BT streaming audiobooks most of the day. I also watched Netflix for 30 min on full brighness. That's better than 8.0 for me, I was lucky to get 5 hrs SOT max.
I would say the calibration is more accurate now, it hung on 100% for too long, so it may appear to drain faster but so far in practice I've gained battery.
Battery life isn't as good as my OP5, but that has a big battery compared to the Pixel 2. I think for it's size it's doing a good job.

I guess you are talking about one of your other devices here, rather than the Pixel 2.
I am getting horrible battery life since going to 8.1
I installed the update the night of the 13th. The past 2 days my battery drains to 20% in about 8 hours. At that point whatever is causing it was stopped by the battery saver mode or the reboot I did when I discovered the phone was in battery saver mode.
Light use at work, staring at my phone is not a thing I have time for. No streaming, no surfing. Just checking texts and emails here and there. Prior to the update I'd get home 12 hours after I left the house and be around 75-80%. Not rooted, not unlocked. Bone stock.
Built in battery stats say 'system' is the culprit. Digging deeper I see Google Play Services app used 70% of my battery from about 7am to around 4 or 5pm this evening. I'd post a screen shot but I didn't to think of taking one before I plugged it in. I just installed BBS and will monitor it for a day.

I thought this was the 5x forum for some reason. Pixel 2 no issues. It was my 5x
A lot of people have brought this up and I too felt like I was experiencing it. I can without a doubt say the battery is draining faster on 8.1. Before everyone starts with "check your apps, bla, bla bla", let me explain.
I recently RMA'd my Pixel 2 for a different problem. Prior to the RMA, I noticed that my battery seemed to take a hit after the update. However, I had already installed various apps and my feelings were purely speculative. As part of the RMA, I had performed a factory reset as instructed and over the course of 4 days my battery performance was still at the worsened 8.1 levels. I should also state that over the 4 days spent waiting for my replacement phone, I installed no apps and only updated the official Google ones that came pre-installed on the phone.
I received my new phone and this one shipped with 8.0. Again, I've installed no additional apps and I have paid attention to the battery over the last two days. As the day goes on, it gets difficult to determine if it is draining any faster. Luckily, my morning routine is damn near robotic. I eat a bowl of cereal and read the same news sites while using my phone. I take a shower and drive in to work. With my original phone on 8.0, I would arrive at work with my battery showing 99-100%. With the 8.1 update, my battery had dropped at this point in the morning all the way down to 94-96% (this drop was consistently reproduced for ~2 weeks). With my RMA replacement I am still on 8.0 and following my usual morning routine my phone is still at 100%.
I know that this test is not the most scientific but I think it is controlled enough to be able to say that something is different between 8.0 and 8.1. I know that others have voiced their concern that the battery performance has suffered. Has anyone rolled back to 8.0 and saw the battery go back to normal? I have a theory about the 8.1 update, but at this point I would rather not share it as it may guide the discussion down the wrong path.
I don't know how much truth there is to this, but some were speculating that 8.0 actually did not report battery percentage correctly, whereas 8.1 fixed this to report correct usage. FWIW, I'm getting to the end of the day pretty consistently with around 50% battery left and 4 hrs SOT, and I think that's a much better measure than how long it takes to drop from 100.
I've heard that too about battery reporting.

I don't think it's speculating. There was definitely something wrong with the battery calibration on 8.0. I'd have two hours of screen on time after taking it off the charger and it would still say 100%. At first I thought it was stuck and not working at all but eventually it would start to drop. As we all know, there's no way you can have that much SOT and still be at 100%. There's no doubt the battery level indicator drops faster when you first unplug the phone after updating to 8.1 but the bottom line is (at least for me) I still end up at the end of the day with pretty much the same battery left as I did when I had 8.0. That's all that really matters to me pretty much tells the story.
The prior 8.0 battery I believe had a bug where it did not report correctly. I remember before I'd use my phone for a long period before it even moved off 100%;
I did the 8.1 update and my battery is much better than it was on my previous phone. I may have had a bad device.
I think that is a bad way to judge battery. It is more accurate with 8.1 as with 8.0 i would get like 30 minutes of screen time some times and still be at 100-99%. if you do that math on that this would probably last me the whole week. But I used to get ~ 5hours of screen time and now i will be lucky to get 4 hours. My routine and work schedule is the same since the update. 8.1 I for sure lost about 1 hour of screen time.
I just got my Pixel 2 and have had it for 3 days now. I did my first test today against my original Pixel. My original was charged up to about 95% and my Pixel 2 was also charged up to 95%. I left my original sitting at home while I took my Pixel 2 to work with me. If I had had my original with me, my phone would be charging right now because it would be below 15%. Pixel 2 is sitting pretty at 67% As for the original that has been sitting on my night stand doing nothing, it's at 56%.
So if there's a battery issue with 8.1, either i'm not experiencing it or I should be at a higher percentage, lol. BTW, both phones all have the same apps and same configurations. Running for about 13hrs each. And as others have said, I remember also seeing that 8.0 was giving incorrect battery readings on the Pixel 2, which 8.1 fixed.
