Battery Temp. & Battery Life( LONG TERM )

[Sheryl John]

First of all Sorry if this question is a repetition. Can't find a proper answer for this at least relevant to latest devices like Galaxy S7.

I play lot of heavy games in S7 like MORTAL KOMBAT X, NFS No Limits, Real Racing, GTA Sanandreas, Modern Combat 5. Might be about 45 mins continuously, twice every day. The question is that whether heating up of device & the battery has any adverse affect/permanent damage to battery life(long term) causing it to last shorter when compared to how it was out of the box even with same amount of gaming. Hope everything is clear in the question.

Thanks

omg stop worrying about your battery temps, just use it, if it dies, get another, simples

But the battery is non-user replaceable. Adding to it is the cost of Samsung service which may end up as a considerable amount altogether compared to just replacing the battery in my LG G4. I know I'm worried too much because I will be using this device for along time. What do you say now?

 

[bIOforger]

Yes I meant a new phone, not the battery, that's what insurance is for.

 

[bIOforger]

Lel, payment in kind maybe?

As a rule, and past experience with the recent Galaxy series, even with heavy use your battery should last several years. The water cooling built into the S7 tends to get fairly efficient with increasing heat up to a certain point. Taking off any case you are using should help matters considerably. I would enjoy the phone and its capabilities without worry.
Having said that, God forbid, you might be one of the 1% that have a defective battery, and in that case it would have gone bad fairly soon anyway. If it does go belly up, I am sure biOforger would be glad to help you finance the insignificant cost of buying a new phone.

We(98% people here) don't have any insurance or not part of any upgrade plans provided by the carrier. So far I'm getting about 6.5 hrs with a single charge. So considering that it's just fine.

@snakyeskm Do you mean 'decreasing' here[...increasing heat up to a certain point....]?

I think the OP has a legitimate question. Batteries do degrade over time. I don't know if excess heat is a factor. I think it is more just a factor of charging iterations, but never-the-less, the S6 and S7 would be better phones if they had access to remove-able battery. Now, if Samsung can bring this feature back with the S8, holy wow, now there would be a phone. Get rid of the glass backing which is a fingerprint magnet, and everyone tends to cover with a case anyways, and add a metal, removeable back panel that is still water proof, similar to the plastic one we had on the S5. Walla, what you have is pretty much a perfect device.

50 years from now, while the energy revolution is in full swing, assuming humans are still around which we likely still will be due to afore-mentioned energy revolution... we will likely look back on these devices as extremely archaic because of their power limitations. "I mean, those dinosaur phones were unable to harness electricity painlessly from stale air. Can you believe people used to have to charge their phones, and running out of charge was a constant concern? sheesh!!"

There's no question that heat reduces the overall lifetime of any battery. That's a given. The lithium-ion batteries in our phones, or any type of battery, create electricity through chemical reactions. (Within limits of course) a colder battery will be more efficient and last longer than a hotter one, it's a fundamental part of basic physics. The plates and chemicals in smartphone batteries don't restore themselves, they just degrade over time.
That said, I think Snakeyeskm's point about just using your phone and enjoying what it can do is an important point and can't be stressed enough. Yes phones aren't cheap to replace and non-removable batteries suck but if you get a smartphone and fixate on battery life too much you're losing out on the advantages of even owning one. Hopefully you'll have moved on to another phone by the time your S7's battery does die out.

There's no question that heat is the enemy to the battery, CPU etc. etc. however excessive caution or worry can easily take the sheen off any product and its enjoyment. Sheryl John is clearly enjoying the S7 and should not be too concerned about it shortening the lifespan of his battery specially since this heating might shorten the life of his battery from 5 years to 4 1/2 years. Who knows if "humans will still be around", especially if Trump gets elected. Those S7 users that are using their phones on the gear VR will heat up their phones in less than 10 minutes to consistently and continuously higher temperatures than any amount of gaming would do for more than an hour.

I too have a similar question. But I don't play games much. My condition is bit different. Quoting the words of Sheryl John. Here is my query,

I kind of lost interest in going for the screen replacement again to Samsung service center for trying to get a perfect screen which has very low probability. Because of doing the factory reset over and over, before repair, after repair(for the sake of getting Google to auto restore apps during initial setup process). Those whole processes of setting up the device, restoring the apps, restoring app datas, reconfiguring the apps one by one, transferring the huge chunk of media files(to internal) gets the device heated up a lot and I notice that battery getting heated up too and I doubt whether this has any adverse affect/permanent damage to battery life(long term) causing it to last shorter when compared to how it was out of the box. Worried about it since I’m planning to use this device for a long time. Should I really worry about it? OR Is there any need of doing factory reset? because if I’m not doing they will be accessing the device at least for conducting H/W Module tests.

PS: Been a iOS user so far and I’ve gone through Apple’s article once regarding battery temperature but I don’t know how it applies to latest devices like Galaxy S7 even though the battery technology hasn’t changed.

I gamed a lot with my Note 2, and the battery lasted fine for the two years I used it before I got the S7 edge. Heat should dissipate faster on the edge though, since glass is a better heat conductor than plastic. So I would worry less. I'd be more worried about leaving it plugged in after full charge and using quick charge.

Honestly though, I'd prefer Samsung get rid of the glass back an bring back the leather back (even if it's false leather) on the Note 4 with a removable battery. I know the trend of aesthetics is for thinner phones these days, but I feel a couple of mm thicker for the S8 would not hurt their sales.

 

[bIOforger]

Why 21%? lol

 

[JovHok]

Anyway Thanks guys. Hope I get a replacement(even after replacement period) instead of dealing with all this warranty bulls***s being a such new phone.

 

[grsbanks]

So I would worry less. I'd be more worried about leaving it plugged in after full charge and using quick charge.

There's actually no need to worry about leaving the phone plugged into a charger. It used to be a problem in the bad old days of Nickel-based batteries (NiCd and NiMH) but we've not used those for how long now?

Modern hardware that uses Li-Ion and Li-Po batteries "knows" that these batteries don't like being overcharged and reduces the charge rate to a trickle when the battery is full. No over-charge can actually happen that way.

Thats not actually the issue, rather the part where some batteries are expanding after much use. There comes a point when even those fail safe mechanisms may fail.
