I have a non jailbroken iphone 4s 16G
Just out of warranty.
Restarts like crazy, but occasionally is stable
I'm a newbie here but is anyone keeping an organized record of issues?
I'm an electrical engineer, not software or ITS but there seems to be some recurring themes I'm noticing
I can give lists of Plist codes, things I've tried etc...
I currently have a nude device setup from scratch, no apps etc etc
The thing that keeps jumping to the front of my mind is that there are some aspects which to me look like a hardware fault, but I suspect it could be as a result of the ios7 update.
Consider this information and fill in the gaps oh tech guru's.
The new ios requires a ton more resource.... correct?
therefore the current drain on the battery will be very high... correct?
P=Ie2.R = Heat...Thats I squared R losses (I cant find the symbols in this editor)
There have been numerous reports of devices getting very hot, heat and electronics do not mix ....correct?
Also the funny thing about electronic components is that despite what many people think they are all a little different, fundamentally they are a grown crystal with some impurities introduced... Correct?
Also damage to a component whether due to ESD or heat can produce a sliding scale of effects, damage can be catastrophic, latent or intermittent....Correct?
So the number of variables on just how much heat/current a particular component was hammered with would be huge, based on usage, ambient temperature etc etc
But the damage would be cumulative IMO.
It might even be something as simple as a connection, dry joint or similar.
I have a suspicion that its something to do with the charging and voltage regulation section of the power supply.... I say this as during the few periods of stable operation my battery charge was completely unchanging, 86% for a full day.
I did a hard restart on the device and it showed 2%.
If the processor thinks that there is no juice in the battery it will shut its self down right? It stops servicing the processes, battery demand drops, voltage rises... oh I can start again now!
it continues to flip flop in a crazy way, heating cooling etc etc, further stressing the device.
Any way thats my random thoughts on the subject..
Pick it to bits, shoot me down... I just want to know what the hell has shagged up my phone
