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!
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.
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).
