Hi I recently was given a second hand mobile fone a Samsung Galaxy s1910 it's a great little fone the only 2 issues I have are that 1 when charging it from either a amazon mains charger or from an onn 5000mAh portable power bank it charges to about 92% then on the mains charger it will briefly stop charging then restart multiple times till it gets to around 97% then it stops and refuses to charge any further with the onn power bank it gets to around the same sort of level then stops and I have to manually start it charging again. However when using a signalex power bank it goes to full charge does anyone know why this is happening? When I got the fone I bought it a new battery so it's not that it's not a thermal thing because as an experiment I put the fone on a cool table top just in case it was a thermal issue. The second issue is it won't let me access this forum or the vintage radio forum it says a secure connection couldn't be established whatever that means however I can get into this site via eMail notifications this a minor irritation but the charge thing irritates and concerns me hope someone knows the answer!
Hi, the first thing is that Internet Explorer has changed their system and the only way I can get onto this forum is via Opera so, maybe download Opera and see if that works.
The thing with batteries is, they have a 'memory'... I guess I don't need to tell you this? Like all batteries... they should be allowed to fully drain down and then fully re-charge them.
There seems to be two types of sites and you can check the details in the address box... one is called 'http' and the other is 'https' the later being more secure and you may need to have 'administer' rights to access this type of site as it is what it's states on the tin... more secure, 's'.
Thanks Tom il have a look see if I can download opera it mite work il let you know speaking of batteries do thes new lion battery's have memory? My girlfriend regularly partially charges her fone very rarely does she give it the full charge and it seems ok but il wait see what others say too thanks

NiCd batteries could loose capacity if not fully discharged (opinions seemed to differ if this should properly be called the memory effect) - but don't think that the case for all technologies - for lead acid types it's actually pretty bad to fully discharge them - Li ion I suspect will be different again (other here will know better than me though).

http and https are two different "transport" mechanisms for communicating with a web site - as Tom say the "s" version is more secure as communication between your browser and the site is encrypted (usually using a secure sockets layer (SSL)). All good sites these days should offer the option of communicating using https (instead of or as well as http) to users in general - it would be very odd to restrict https access to administrators. The encryption system (e.g. SSL) often undergoes updates and changes to keep it secure - so it might be that your system is a little out of date and can't cope with stronger encryption that some sites might now insist on. (A lot of older smart TVs stopped being able to play YouTube videos when YouTube insisted on forcing everyone to use https.)
Ajjewsbury ide like to say I understood what you said about http and https but honestly I didn't really understand I will ask my girlfriend as she seems to understand it all better than me also il have a play with my fone see if I can sort it myself x Kelly
Since this forum moved it is now located on a Microsoft platform. Microsoft stopped supporting I.E. some time ago meaning they no longer issue security patches to it, so maybe they block access to it using IE now.
Shortly after I bought my (Sony) phone, they issued a software update, reducing the maximum charge level to prolong battery life. I have read elsewhere that for maximum battery longevity, it should be operated between 20% and 80% of its maximum, so I wouldn't worry about squeezing in the last 3%.
My understanding is that Li-ion batteries do not have memory, and the advice above is correct. Li ion get most stressed when they are fully charged or fully discharged and 20%-80% is regarded as optimum for long life.
Li ions have a limited number of charge /discharge cycles, interestingly 20-80%only counts as 60%of a cycle, not as 1 charge/discharge.
Incidentally, I don't know which part of the country you are in, but Samsung have a number of centres where you can drop in for free advice (just as Apple). There is one in Kingston on Thames, near to me.
Thanks David now that I know that Lion battery's don't have a memory I can stop worrying about full charge discharge cycles interestingly I left my fone plugged in yesterday and then had to go out I left it for around 3 and a half hours and it was 100% charged when I got back I think it may cycle it's charging when it gets to a certain temperature yesterday was cool and cloudy so maybe that had an effect. I'm in Weymouth Dorset and I've never seen a Samsung or Apple advice centre here ide probably have to go to Bournemouth for that
