My battery has a poor duration

[maykelbembibre]

I did the test of Game Boy playing at minimum brightness from 100% to 1%. Samsung's 2100 mAh battery died at 10h 30m. I don't understand it, when I was using normally that phone, it didn't offer me more than 4 hours with screen on and now it takes more than 10.
Innos removable battery died at 11h 30m. It took 1 hour more than the Samsung's. But is a 3450 mAh battery facing a 2100 mAh one. It shouldn't have more difference between the times they can stay alive? 1 hour more seems little to me taking into account the mAh difference.

S3 is smaller screen and lower res and lower power. That is the rest of the difference. Now you still have the full internal too

Thank you all for the information given. GottaGetX, what you said makes sense to me. Then, can the hardware difference make a battery of 3450 mAh to last only a 10% more than a battery of 2100 mAh? Is there so much difference between the hardware of a Galaxy S3 Neo and an Innos D6000? I thought that both phones were similar and because of that I thought that the Innos D6000 removable battery would last at least a 50% more than the Galaxy S3's one.

Also, MegaManX stated that his removable battery held for almost 6 hours from 100% to 50%. With mine the most I got was 3 hours. Playing video or Game Boy my phone battery goes well, but using WhatsApp or Chrome battery drains really quicly.

[maykelbembibre]

It is definitely. I am going to return the phone and beg my money back. I have given too much opportunities to this phone and this is the limit. It marked me a 19% of external battery, 98% of the internal, then external went to 0 and internal to 0 and the phone turned off. This has happened in only several minutes. This phone is spoilt, or bad manufactured or anything else. I don't want to know anymore about it.
I thank you very much for all your help and directions on this time.

Could you please recommend me an smartphone of a reliable brand which has a good battery lasting?
When I bought a mobile from a not known brand as Innos I knew that I was facing some kind of risk because as a not very strong brand it is not supposed to have a lot of resources, quality control, etc. So I return to the well-known brands with presence in my continent, Europe, to not to be exposed to more troubles.

would you believe most of us, if we said that our D6000 are working great and the battery lasts long? if you can believe us, then it might be a good idea to return the D6000 and buy another from a known good seller, like gearbest.com... but of course there are no guarantees... even iphones have hardware issues, although not as much.
Cheap, Quality, and Fast, are never found together

but to give you a recommendation, i would suggest:
Samsung Galaxy Note 3 with a 10000mah zero lemon extended battery pack.
It will be thick and heavy but it will be fast and last you long time.
Many phones have extended (non official) battery options, just check amazon.

The China phones are beginning to be incredibly inexpensive, good quality and fast as the most expensive flagships.

I had a problem with my d6000 when both batteries to 0 and internal wouldn't charge. So I left it alone for 2 weeks, then its back to normal and never had the problem again. I still don't think maykel has a battery life problem. 10 hours over 2 full days is normal. Yes, this down to 0 is a problem, but I think that's possible with all the d6000 and several people complained about it already.

Have you tried charging to 100% then battery calibration?

Asus Zenfone max with 5000 mAh is available at gearbest.com and they have a 45 days refund warranty so if I don't like it I return it XD. What do you think about it?Asus is a most known brand than Innos and that gives me some reliability. Innos is a not mature brand and so that the fails we are reporting.
Galaxy S3 was giving me 5 Internet browsing hours with 2100 mAh while D6000 gave me 8 hours browsing and WhatsApping. 8 is not the triple of 5 so I think the 6000 mAh were not true. I rate the two together D6000 batteries at 3600 mAh, according to my calculuses.

Again, you've forgotten the S3 has a smaller display and less resolution... And you got 10 hours, not 8. As well, you did the test on the first cycle. The batteries have been tested and are truly 6000mAh.

The biggest issue with your SOT test is that you did the test over 48 hours.

You want to do a real test, charge to 100%, take off the charger, use the phone at 50% brightness on WiFi and don't stop until both batteries dead. You will see 12 hours SOT no problem. A 3600mAh battery will come a bit more than half of that.

The D6000 has some failings, but battery life is not one of them.

[maykelbembibre]

Thank you I know you are right, that is why on the last days I made exactly the test you are saying. I charged both batteries to the 100% and started using WhatsApp and Internet browsing. Stayed like this for two days approximately. Both batteries died at 8 hours of screen. It is what happened to me. Perhaps my batteries or my phone are faulty and yours not. I don't know. Also I checked mobile data was off, bluetooth off, brightness less than the middle... and so on. I already have had enough problems, so I have to buy a phone from another brand which is more known and forget about all of this worryings. What do you think about Asus Zenfone max?

Also, I have to say that battery life is not the reason for which I return this phone. I would have got along with 8 or 9 hours of internet browsing. It is not very bad. But the marker of the battery does not work properly as I said on a previous post. And that is a kind of failure I do not accept. Imagine you are on a car on a motorway and it says your tank is full and suddenly the car stops because it has no gas and marker was failing. That is what happened with my D6000 and I do not accept that.
