I noticed that my dad's 4000mAh battery lasts longer than mine (4000mAh too) and I use laptop to charge at times so I don't know if that's the cause

75 views and no response? Either people are dodging attacks after comments or they just don't wanna talk. Anyway here's my opinion; without going into much geeky stuff about the amperes your phone takes to charge, chargers generate specific level of power ranging from 250mA(or below) to 2.4A (or above). So the higher it is the faster it charges (mind you if your battery capacity is not really up to 3000mah and above or uses fast charging [which still applies to 3000mah & above], I would say it's a waste of effort buying a charger above 1A cos it won't take above that level or probably doesn't need it). That being said laptop USB port are designed specifically for data transfer: flash drive, memory card (card reader) or direct connection with a device and although, it will be charging simultaneously but it won't be charging really fast at all except it's a Nokia Torchlight.
One thing (that I noticed) with smartphone is when you use lower power-generating source (a.k.a charger heads) to charge it tends to weaken the battery life and in this case pc is one of those slow-charging source. Let me point out too that the type of USB used plays a major role too: we have the silver pin and gold pin, the latter is the best to use.

I say conclusively that any smartphone that has above 3000mah battery capacity needs it "follow-come" charger or good power banks (some might argue that power banks does the same harm as pc, I will reserve my comment on that) or a good charger that meets the same specs of the "follow-come" or slightly above wouldn't do any harm; let's say if you have 1.8A charger, getting 2.1A isn't bad (so far the battery capacity needs it (I say again 3000mah above, especially for 5000mah like homtom HT50 has and 6000mah like the Partner mobile ps 2 or the gretel GT6000. Pls don't think itel is among them o, I'm yet to see any of their devices with high ba3 capacity that has fast charging feature)

So the summary of my essay is "Yes, charging a fone with laptop or desktop weakens ba3 (or spoil if you prefer that term).

I rest my case

The only problem you gonna experience, is slow charging

I think it's the other way round. charging phone on laptop spoils the laptop battery.

I don't think it has adverse effect on the phone, I've used laptop to charge my phones several times and the batteries weren't affected. I can't say the same for the laptop battery though.

Yes, especially if it's a strong battery

I lost my Techno M7 battery to this practise since then, I've tried to use only public electric power supply or very good generator for charging my phones.

It spoils the phone and system battery.. .chikena

Some people are naturally confused about life in general.
Patiently waiting for the day someone here will ask "if I slap a three star military general, will I die?"

Yeah.. It weakens the battery over time..

I don't see how the duration of the charge would relate to whether or not it's harmful to the smartphone. I have never seen any documentation that keeping a phone plugged in perpetually (whether plugged into USB, AC or DC) would cause any harm to the phone itself. An argument could be made that it's harmful to the battery.

Constant charging is not generally a problem for Lithium Ion Polymer batteries (which most new cell phone batteries are). It is in fact better to frequently charge them, and not let them fully discharge.

One factor that does degrade the battery life of all Lithium Ion batteries is heat. The more heat it's exposed to the faster it will lose capacity, so I can see how keeping it plugged in may keep it warmer longer and theoretically degrade the battery life.

It does not

More explanations please

I think it affects the laptop's battery more.


What do I know sha

Just observing

Let me just throw some light on what someone already stated on this page. What matters most in any charging source is the power output. The voltage multiplied by the current gives you the power.

Most chargers will tell you 5v but the current will be 0.5A, 0.8, or 1A. This isn't really an ideal rating for a phone whose capacity is higher than 3000mah... Especially if you have damaged the original charger. An ideal charger should give a total of 10W ( say 5V, 2A) upwards.

The next most important thing is d cord. Lol most people don't know the cord is important. Failure to use the specified cord could cause overheat and damage your phone for obvious reasons YeA. In fact any charger that's not from slot, Samsung office and the likes is a cheap imitation from china and only the cord is about 1k5 upwards

To the main question, charging your phone with anything other than the main charger is a kamikaze in phone terms

no no no no
get a good USB , Amazon or Kodak USB.
u re good to go.

Depends on the Laptops Battery Capacity

Yes yes yes..I can't explain why but it spoils both the phone''s battery and the laptop's battery...changed my laptop''s battery twice within 2 years...pretty crazy..probably someone can shed more light

Apple and Samsung laptops have a good battery capacity.
And I think HP does too.
The rest I don't know.

I need to know this too... I do that alot

Are u using gionee



Yes it spoils ba3, my ba3 is spoilt thanks to laptop charging with a useless cord (after the original cord spoilt)

Mint question

those that made phones with their specific chargers are they mad? Or does 'follow-come' not make sense to you?

No it doesn't effect mine

My dell inspron I bought since 2011 Is still saving my gionee P5w and bb10 are in good condition

I haven't used generator less than 8kva to charge my phonez ND laptop

For me I haven't noticed any side effects
