Re: S8 battery

Your cell signal doesn't seem that good, at least not in those screenshots. Poor signal is notorious for eating battery. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:


1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).


You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.

Cell signal in screen shot is at home so is always low, during day I'm at work on road no normally pretty good signal.
My email in 14 min of use used nearly same amount of battery that 1h on screen time.

Re: S8 battery

Does the battery drain at the same rate at work compared to at home?

Well sort of, I use phone at work more due to phone calls, I think the extra power gets used by std Samsung email up along with Google services

Re: S8 battery

I would still suspect that poor cell signal is part of the problem. Unfortunately, there isn't much you can do about that besides switch carriers, or check with your current carrier to see if they offer signal boosters.

Ok how can I check this how long the phone was with out a signal in that charge cycle? It use to show in once you press on "cell standby" but it don't any more?

Cell signal booster won't help me because I'm on road moving most of the day.

Re: S8 battery

Right, I had previously suggested installing GSam Battery Monitor, which does have a cell signal strength graph.

If the signal is only poor at home, that's where you need the signal booster. It may be that overall, your drain is occurring at home (unless you specifically notice that the battery also runs down quickly even in areas with strong signal).

Is not at home, I wake up get to work and phone is not charging at all, the screen shoots was taking after I come home from work, so phone was maybe used for 5 min at hime, I understand that there is some area on road where the call will drop so I know the phone will lose signal few times a day, but still very annoying that it just drain the battery.

I had the GSam monitor installed by I can't figure out what graph you talking about.

Just watched YouTube where someone saying to reset network settings and clear phone catch solves the problem, will try that is well.

Little update, phone gets lot hotter now when just browsing ect., contacted Samsung and they recommending to have a look at the phone.

Browsing temps reaching 50C+ and secreen off is at 31-35C.

I didn't factory reset the phone and just wonder if is worth doing it?

 

[B. Diddy]

That's pretty warm for just browsing. That can happen if the signal is poor, but also if the battery is starting to fail. A battery can fail if it's defective, but it can also start to fail relatively early if it's habitually drained to zero (or close to it), rather than recharging at around 30-40%. Do you typically discharge it really deeply?

Most of time around 20% in all honesty I had s5 with original battery for 3 years and didnt have much of a problem, this phone after 11 months as I checked on contract showing signs of wear, better go and check it out. Just replying this battery hover at 30c and rising as you can see at end of graph, will post screen shot after 1h browsing see what that app shows.

I can understand higher temp but I don't even play any games on this phone.

 

[malenki22]

Well I have been using phone for 1h but I did unistalled couple of apps to do with widgets and battery temp behaving, will keep a eye out as I can't get to Samsung store until weekend anyway see if temp will get higher, for now I think is acceptable. Phone feels cool now when touching.

Could any widget app make the battery temp higher? Or any other apps associated with widgets? Also running substratum but I don't think that's a problem.


Hmm just not sure what the problem might have been.

I suppose it's possible a widget could be a problem, if it were constantly (and inappropriately) accessing the web to refresh data.
