[Galaxy S6 General] tmorterlaing:
So, a bit of a longer response, but I'd like to know what's going on.

Firstly, I think we should all stop going on about how good/bad the number of MaH is. The reason this confuses me is because the HTC One M8 is renowned for having a VERY efficient battery life, and it 'only' has a 2600MaH battery. My logic would suggest if one is happy with the battery life in that phone, the S6 should be getting similar results as it has a virtually same size battery.

The primary difference between the two I guess is the QHD display on the S6 - but the AMOLED is supposed to be much more efficient, and the processor is more efficient, and the 14nm is there, and the software is now a similar 'lightness' to Sense.

So my first question is, why are people not getting good results? This to me strongly suggests that the battery size is less relevant than software optimisation, whether it's Android L (as previously mentioned here a few times) or the bloatware being problematic.

Secondly is the 'consistency in reports/ review' question. I understand mileage may vary, and please let me make it clear I UNDERSTAND BENCHMARKS ARE OFTEN NOT THAT HELPFUL OR ACCURATE. HOWEVER. It doesn't stand to reason for example, that a computer than is the top of EVERY benchmark done is only an average speed when compared 'in real life'.

So, with that said, let me point out some of the VERY confusing reviews and case studies:

iPhone 6 Battery life (says its good): http://www.trustedreviews.com/iphone-6-review-battery-life-and-verdict-page-6

S6 Battery life (basically says it's bad): http://www.trustedreviews.com/samsung-galaxy-s6-review-battery-life-and-charging-page-4

BUT the SAME WEBSITE says the S6 is better: http://www.trustedreviews.com/opinions/samsung-galaxy-s6-vs-iphone-6

Same again here with TechRadar: http://www.techradar.com/news/phone...-phones/samsung-galaxy-s6-vs-iphone-6-1286508

But the iPhone 6 is MORE than adequate apparently? http://www.techradar.com/reviews/phones/mobile-phones/iphone-6-1264565/review/5

But the s6's battery is only JUSt good enough: http://www.techradar.com/reviews/phones/mobile-phones/samsung-galaxy-s6-1285636/review/4 (admittedly a slightly better review than the trusted reviews one).

-Not picking iPhone for any specific reason btw, but this is a good representation of most of the latest phone reviews.

Onto some benchmarks now (don't yell at me, I won't listen): http://www.trustedreviews.com/opinions/which-phone-has-the-best-battery-life

Firstly you'll note that despite the above review comparisons, the iPhone 6 outlasts all of them - however for the most party the S6 comes in second place (or third, if you count the iPhone 6+). I get that neither the G4 nor the M9 are rated as being battery beasts, but the 'issue' of battery doesn't seem to crop up in their various online reviews for the most part. Most people seem happy with those two. Also browsing the forums here the G4 at least people seem to consistently say about 4-5 hours SoT, which IMO is actually pretty good, as that's what my M8 was getting and I was very happy with. I could probably push the M8 to about 6.5SoT if I was careful, but for average use 5 hours is 'good' to me. I know some people in THIS thread are saying 5 hrs SoT but the backlash on them is much harsher from other users, and the spread of reviews is much wider (everything from 1-5 hours SoT), which is confusing.

Most M9 reviews seem to say the battery is roughly on a par with the M8 - again, this is therefore pretty good IMO, but tests shows the S6 is EVEN better... but this is apparently a problem?

There's also many conflicting youtube reviews. Marcus Brownlee for example reports similar findings to what I've written above- the spread of battery life is odd and leans towards 'bad'. But then Geekanoids says it will easily last you through a day with medium to heavy use.

I could go on, but given how negative people are to the battery life on this device compared with the others, one can only assume a few possibilities perhaps:

1) Software issues must be quite prevalent on the S6, and optimisation is something Samsung needs to SERIOUSLY work on for a software update (but based on the M8 the potential for good battery life is CERTAINLY there).

2) The battery life on this phone is perfectly fine and people are just bummed it doesn't have a replaceable battery or that it isn't quite as good as its predecessor, even though it has a quicker processor, better camera, better audio, looks nicer etc.

3) The battery on this phone really is bad and all the benchmark tests are absolutely rubbish.

4) HTC and LG owners are inexplicably much more forgiving to those devices, as are reviewers (almost like "Samsung have produced a good phone so I need to really overstate the average-but perfectly-good battery life and make it seem like an actual issue, when in realty its perfectly fine).

I just got my S6 yesterday but haven't had a chance to test it properly - it's not fair unless I give it a day or so for various updates and app installations. I also had a G4, but there was dust under the screen. Then I got a replacement which had the same issue, so I lost faith in LG after coming from an EXCELLENT phone (M8). Especially when I did an A/B listening test with the G4/M8 and found the audio to be pretty awful (audio jack out I mean, I couldn't care less about the speaker. The S6 has an excellent audiojack out) - but now I'm off topic :D
