You're not really losing it, it's just that the battery reporting is poor so when you reboot it is probably "catching up" and showing you the real value.

Do you think so? But when I charge the phone it is off... And charge all night.. And when I turn on in the morning I've that problem..

..Or you could look at it this way. Rebooting takes a significant amount of power and thus it will be lost after it boots up.

Hes not rebooting or powering off the phone, from the graph it looks like he is just turning on the screen and taking it out of deepsleep/idle mode.
The screen is a HUGE battery hog and if you have high brightness you can destroy the battery quickly. What is your brightness set at OP?

Nexus 4 uses a lot of power to turn on, reboot. On top of that, battery display is not correctly informed. Should be fixed in the next update.

Media scanner? I think I had a corrupt file or something once because media scanner ran for like 2 hours after boot.
Sent from my Nexus 4 using Tapatalk 2

Could be something like media scanner, that's a good suggestion. Because you certainly shouldn't be losing 5 to 10% on booting.

I don't have any files at this time..how can I check? Do you think a full reset could help?
Inviato dal mio Nexus 4 con Tapatalk 2

No pics, movies, music? Mine was obvious, it was the highest battery drain in the battery use monitor.
Maybe fully charge then shut it off, unplug, and turn it back on leave it set for 5-10 minutes and check on what is eating battery. I assume you've done this put you haven't mentioned any apps of android system or anything eating battery.

I've installed gsa battery monitor...I'll try to find the problem..
Inviato dal mio Nexus 4 con Tapatalk 2

I also experimented similar strange battery behaviour last week;
I started a stress test with 35% of battery and stop it when level reached 10%. As battery level continued to drop (within 30 sec) to 7%, I checked running apps and closed everything, but after another 30sec (or 1 min) phone shut down after reaching 1%. So to summarise, I also experiment lost of 10% of battery within 1 or 2 minutes.

There's another thread from me here on the same subject. I think it's down to crap battery stats on the phone side. I placed a call with Google and they claim they've never heard of a large battery drop on boot before.
For note I charge my phone up every night when i get back home and power it off on 100% charge before going to bed. In the morning on starting up I get a battery reading of anything from 82-99%. Note tehre appears to be no difference if the phoen is left off for longer periods of time (i.e. for me weekends when i'm not getting up for work hours being a lazy sod)

I didn't resolve too...and I didn't find the app...maybe the problem are kernel wakelocks

3500MaH Spare BATTERY SPOTTED in the WILD!

Hi Guys,
Did anyone come across this battery? http://www.ebay.com.my/itm/Quality-...850?pt=LH_DefaultDomain_0&hash=item2ee3147afa
its a 3500mah battery.... how would you know if it is not safe to use?

i think this is a fake...
Do not shipping to germany is a indicator that they have big Problem with the german law... think, do not buy

For $10, it will attract some curious people. We will just have to wait and see the review and feedbacks. But when demand goes up, price goes up.

Then the phone will light on fire as a new and improved feature of the battery ahaha.

who's gonna be the first to try quick charging with that battery?

OK, I've said it in the past... I'll say it again...
Don't you all think that if LG could, they would have implemented a 3,500 mah battery instead of a 3000 mah battery? Especially seeing that it's a minimal cost... If it were truly 3,500 and could withstand the 300-500 recharges as its current battery can hold, then I truly think they would have done it. EVERY review simply states "it's big, but not the biggest in the new flagships" or something of the sort... LG could have had it says "bigger than any other flagship out there!"
This is a total fake. If it's real, that charge won't last more than 20-30 charges, tops, at 3,500 mah.

Actually I have seen manufacturers shy away from bigger batteries to save a few $ (even if it isn't that much). But yeah, this think is probably 2900-3050 mah. I have had multiple Chinese knock offs and the usually work but at best they match the original battery unless they are massive (like my G3 6500 Mah). Only way to know is to try it out and if it sucks get your money back and let everyone know. You'll only be out a few bucks and you might have a battery just as good as the original. My 2 cents

Battery life is fine on this phone...

I have had multiple Chinese batteries, and while they last a while for the first few charges, after that, it's all downhill. They aren't as reliable - at least not these no-name brands. I'd stick with Mugen, they make very good batteries! But hey, at least at that price you can get a battery that you can keep in your bag or something as an emergency. I didn't say it wouldn't work! I just said that the capacity of 3500 probably isn't true.

As the rumors are for 3000 mAh battery. So what are your expectations for SOT and standby time. Hope they resolve the 2% drain per hour issue of Galaxy S6. This is the worst standby drain I had with my phone. Let's hope sammy improves on this for S7.
Sent from my iPhone using Tapatalk

So the leaked specs & handling video confirms that it is in fact 2800 mAh battery. OK still better than the 2550 mAh in Galaxy S6.
http://www.gsmarena.com/samsung_gal...e_announcement_specs_confirmed-news-16679.php

I'm thinking we could expect a full day of pretty heavy usage on the S7. As for the S7 edge, I'm hoping for 2 days of medium/heavy usage.
With increased battery sizes, improved display efficiency, OS optimizations, etc. I don't think this is far fetched.

I also hope that in use it would have better SOT than GS6. Like mentioned earlier, my biggest concern is standby drain. For my GS6 the standby drain is consistent at 2% / hour regardless of whatever I disable / enable. Even package disabler pro bears same standby by drain. In contrast my iPhone 6 with exactly the same apps installed will show only 1% standby drain / 4 hours.

As more leaks and rumors flow forth on upcoming "Always on" screen of Galaxy S7, it's easy to become prematurely concerned about what it all might mean for the battery life. Let's wait and see.

I dont believe the report about the battery being 2800mah in this article which was written today says its confirmed 3000mah
http://www.talkandroid.com/285823-samsung-galaxy-s7-leak-talk-android/

How does that link in the OP prove anything about the size of the battery?

This is the only info I could find. You are welcome to add in any new information you have.

It's settled, 3,000mah for the S7 and 3,600mah for the S7 edge.

next thing I wanna know will the batteries be removable?

Don't think so, look at the leaked video and pictures. The design is very similar to Galaxy S6.

Now LG has upped their game with G5 on removable / expandable battery. Fingers crossed for how Sammy plays it.

So it's official that 3000 mAh for GS7 and 3600 mAh for S7 edge.

The screen features an Always-On function, which will draw 1% battery charge per hour.

I've read that it's actually 0.5% per hour (thanks to AMOLED), and it will actually turn off if proximity sensor is covered (i.e. if it's in a bag or pocket).

The lower the better for consumers

Solid

Second day, almost 6hrs SoT and still 35% battery left.

Can we maybe also add what apps we're usually using (what apps use most of the battery)? This would be pretty interesting to know.

The sot's doesn't look really well. Or are you guys only played games? For a 4000mAh battery with Snapdragon 625 should be more possible.

Bit different, but I did an hour test of streaming youtube on WiFi (everything else closed, sync off, stamina off, etc) with medium brightness and medium audio through speaker.
It lost only 7%, so looking at 14 hours watching YouTube in this way
Pretty good I reckon.
In general use the couple of days I have had it the battery seems really good.
Edit... After a couple more days use my typical Screen On Time is approx 10 11 hours for general usage (mainly on WiFi)

Hi guys , this is what I've got in 2 days of use
:silly:

Less 3G/4G, more WiFi

Thanks to Greenify and Magisk, and low brightness when indoor.

Lol, I really am a light user, I've only charged it once in 7 days since the initial full charge. I get 5 days between charges so I'm loving the big battery, it's surprisingly light too.

11hr15m SOT. Coming from Pixel this is unbelievable.

3 days, amazing

Third charge. Stock system, running Octobre update.
Brightness set manually during usage, everything ranging from 5% to 100% when outside.

Hi, May I ask you how do you manage to get 6-8 SOT because I have the phone since a week with global ROM installed and I get around 4 hours ( the same I had also before with Chinese ROM)

4 hours is reasonable, person with 6-8 hours SOT will highly likely have different usage to you.....
Turn brightness down, install another kernel, don't use high demanding apps as much, close and turn things off when not using, use power saving apps etc

I can't believe that my mi mix 3 has only 3200mah battery

I also had battery issues. Sas barely.using phone and in half a day telephone asked for.charging. whaat i did was disxharge to shut down then charge to 100% without turning on the phone. It helped a lot. Ove read aomewhere that this method is food once a year for phone battery because it helps to calbrate the energy levels in the battery.
Also it.is good. to use as dark pixels.as u can becausw.the.brighter the more.energy ia going to be used.
Also disable.services you dont need(wifi,gps,mobile data,nfc, bluetooth background processes, anything thhat is using your battery energynto.work.
With advices in this.thread you can prolong your battery by like 40%. Can confirm that it.helped me.
Just do.some reasearch on enerfy saving in a smartphone.

I've got mine for around 3 days and the battery don't last even half a day, it usually lost 10% in 2h. while in idle, I have AoD, Bluetooth and data, but I'm quite sure that it's not normal.

I have MIUI 10 Global Stable, last update.
In the meantime I turned off AoD and now it's fine, I've found out that the screen never turn off even when inside the pocket.

I was able to get 6 hours of sot

I recommend disabling the option to use adaptive battery, at least it improved here after I deactivated it.

On PE I was able to get 8 hours of SOT right now I'm testing out AEX seeming it was March security patch I'll keep you guys updated on it
Edit: same with PE around 8 hours of SOT
