My battery has a poor duration

[maykelbembibre]

I have finished my first discharge cycle with external battery at 2% and internal at 20%. I had to charge them because this afternoon I am going out. 10 hours of screen on was what I had. I think it is good, but I hope the time gets a little better when more cycles done. I had 5 hours of awake time. It is slightly worrying.

Sometimes reboot fixes the kernel wakelock. Just turn off and turn on again. 10 hours over 2 full days and still had 20% juice? That's great man. Enjoy and be happy.

Bad news. You know that I was having battery issues with my new Innos D6000 and because I was fed up, I tried to compare its battery life with my Samsung Galaxy S3 Neo (2100 mAh, very little battery, isn't it?). So I charged both phones up to the 100% and I started my favourite test in both of them: a Game Boy Color game that repeats to the infinite a sequence of demo playings. I leave both phones for a whole night, with the same brightness (minimum), off-line mode, bluetooth off... Both phones were at the same status. When I woke up, samsung was at 48%. Innos D6000 external battery was at... 50%. Why? Is defective my Innos D6000? I don't believe that a 3450 mAh battery has almost the same performance as a 2100 one. A bigger battery should last for a bigger time. Or am I wrong? The fact is that both phones discharge at the same rate, very quicly, but one has 2100 and the other 3450. My Innos external battery is barely making a difference with the 2100 mAh battery of my old phone. And for the internal battery of the Innos, I have to say that it discharges so quickly that you can barely use it for 2h 30m. I need your expert opinion on this issue. Thank you very much.

You didn't have any battery issues. On your first run you got 10 hours screen on time over 48 hours, and you still had 20% left on internal. This is great. I think you're just determined to be sad...so nobody can help you if this is what you're determined to be.

% means absolutely nothing. Charge both again to 100% and take them off the charger. Run the test again with the screens at the same brightness level (look at the screen, dont just make it the same brightness %) until both phones die.

I had already looked at both screens to ensure they had the same light intensity.
Yes it is true that I got 10 screen hours but much of them were with the Game Boy test, which only takes 10% per hour. Data mobile on and Whatsapp/Chrome takes about 20% per hour so I think that way I would not get more than 8 screen hours with both batteries. Is there any way to know who drains battery? An app, a service or something like that. GSam only says the culprit is Android system being responsible of a 65% of battery consumption but this is very abstract.
You are right I am determined to be sad, but the fact is that I am coming from an horrible S3 with only 2100 mAh to a phone that has almost three times that and I was expecting a better performance.

EDIT: I've just got the results of the test until both batteries died. Samsung phone turned off itself at 1% while Innos removable battery was at 8%. It is strange there is so little difference knowing that innos has a huge 3450 mAh battery and Samsung has only 2100. I expected that when Samsung died, Innos had still a 30% or something like that. What is your opinion?

MegaManX, don't pay attention to the test that I explained on the bottom of my previous post. I don't remember and I am not sure if both phones were exactly on the same conditions. If I get enough time I will try to repeat the test again.
I think you may have right on what you said about that the percentage does not mind. Innos removable battery always discharges at a constant rate. Nevertheless, It seems to me that Galaxy S3 is different, when I was using that phone I think that battery discharged constantly until the 20% and then went to 1% very quicly, but I am not sure. In case that was true, it could mean that when the samsung battery dies suddenly from 20% to 1%, Innos one could still have 25% or so. Sorry for my bad English. I can speak it well in normal circumstances but I'm not quite as good with the language when it comes to explain technical questions.

Yes, that can happen with a lot of phones. It's because of calibration with the voltage.

For Lithium, a battery should not discharge past 3.5V, but the Innos D6000 is very difficult to tell because of the dual-battery system.

This is why I said charge them both to 100% and time them from 100% until Galaxy S3 shuts down and Innos D6000 switches to internal. Remember the S3 is 720P, so depending on what you're doing, that could make a difference. And the display is 4.7" vs 5.2", which for sure makes a difference.

sounds like you have gone thru 3+ cycles and still having doubts about your battery life.
you probably do have a crapy built d6000, it is made in china
but there are ways to cancel out known issues. first fully charge your d6000.

see if it is your cell reception 3G sim - remove your sim card, turn on wifi and play a 2+ hour youtube movie on max volume and brightness, if your happy with how it lasts, you might has a 3G cell tower reception issue where the phone constantly tries to reconnect to your local cell towers.

if not... then thats all i can think of sorry :/

I have tried the phone in airplane mode and duration results are exactly the same.
I thing duration is bad, because with around 30% brightness, it loses about 20% each hour when navigating through the Internet and using WhatsApp with mobile data. I have not tried on a wifi connection yet. Whay I know is that losing a 20% each hour is a crap, at least in my opinion.
All the time I am talking about 3450 mAh removable battery. It is a huge battery but I don't notice a better duration that with the Galaxy S3 Neo which has only 2100, that is the reason for which I am so anxious. I stepped from 2100 to 3450 and I am losing the same percentage each hour. It is awful. I don't understand anything.

Everything is made in China. There's nothing wrong with his d6000 batterylife. 10 hours onscreen over 2 days is a good result.

His other tests are peicemeal and in bizzare ways.

As already said by MegaMan, charge both batteries to 100%, take it off the charger, use the phone normally from 100% to dead and check screen on time. All this other talk about 20% per hour is meaningless.

I am used to base a battery's capacity on the velocity the percentage comes down. With Samsung Galaxy S3 Neo, it lost a 20-25% per hour, so in 4 hours its battery was usually dead. With Innos D6000 removable 3450 mAh I expected to lose around a 14% per hour. Just do a rule of three. The fact is that with the Innos I am losing about a 20% per hour and it does not make sense to me.

All these velocities are based on a low brightness (about 33% of the brightness bar), frequent wi-fi use, occasionally mobile data, and WhatsApp and Chrome as most used applications.

I will try what you say and use the phone for a discharging cycle without all these rare tests and see what happens and how much screen hours will I get. But my estimation is 5 hours from removable and 3 from internal: 8 total hours. And I do not like that estimation. 4 hours of screen with normal use offered Galaxy S3 Neo with 2100 mAh so Innos D6000 must offer triple: 12 total hours. I hope the 8 hours estimation is wrong.

I have made a test playing a long HD video from Youtube using wifi, middle brightness, middle volume, full screen and in 1h 30m external battery has gone from 19% to 19%. That's it, it has lost 0%. Seems great and weird...
