Did the battery charge level, shown on the lower right of the display, ever get up to High?

Do you have the Auto Light (A EL) turned on? Maybe the light is activating with the watch under your sleeve, draining the battery.

If the battery charge level shows High then immediately goes to Low, it's possible the battery is defective.

 

Sounds like your battery isn’t charging properly. What’s the last 4 serial numbers on the back plate on your GW7900? These numbers tell you the exact date and year when your watch was manufactured. Maybe your watch was sitting idle for many years causing the batter to drain. Check it out and let us know. You may want to put your watch for a week or two in your window sill so it can soak up lots of sun to revive the battery.

 

As you can see in this table from the manual, even if left in sunlight, this solar watch whose battery went flat will need almost 12 days (7+88+24 hours) of full sunlight (assuming 10 hours each day) to become fully charged again when located behind a window. If charging outdoors, this will be significantly reduced to 2.5 days (2+18+5 hours). Charge it indoors with just overcast daylight and it'll require 24 days (13+180+48 hours).

 

How old is it?

 

can we see picture of the G to know it is real before going further with the diagnosis ???
1/ like Gary said: you might have turned on the Auto Light feature
or
2/ didn't give it enough time for charging
or
3/ the less likely but possible reason is battery defect

 

Yep, I've had to leave "dead" solars for literally weeks before they get to high.

A few days is nowhere near enough. Your High reading is a false one. If given enough strong light for a short amount of time it can jump to a high reading but it won't stay.

You need to be patient with it and leave it sitting in light [emoji106]

The irony is that changing the batteries on non-solars only take a few minutes. LOL.

Years ago, I had a g-shock exactly like that. It simply won't charge properly. Threw it away and was done with it.

You can change the battery on a solar just as easily as on a non-solar, but the battery costs more.

 

Nowadays rechargeable batteries last for a very long time. You can get 15 to 25 years of life. I own 4 solar atomic Mudman G-Shocks that I purchased brand new in 2007 and all 4 still have their original batteries in them after 14 years.

 

I have 2 elderly x Citizen Skyhawks Eco watches, one bought in 1999, and the other in 2000, both still charge great!

 

I've attached the pictures of the watch, and yes I do have the auto-backlight enabled. How does one disable that? Thanks for the help so far! I honestly didn't expect such a hasty response.

Spoiler: watch pics

 

Power Save On/Off is just one of the options when scrolling through the Modes after hitting the Adjust button 👍

 

I did some research and decided to put up my watch to a lamp to charge. Surprise, it actually works! It's currently charging easily, and works perfectly.

That is a surprise! Lamps are rubbish compared to the sun, in quarter of a century owning 'solar' watches, I've never used anything else apart from the sun, and I live in the UK LOL

 

You don't have Auto EL enabled, so don't worry about that. We mention it because it will run the battery down faster than any other feature. It won't turn on if it detects moderate light but in the dark under your sleeve it will always be activating the back light needlessly.

If you hold B (top right) for 7 or 10 seconds it will toggle Auto EL and you will see that segment is on indicating the feature is active.

 

So if you charged it under a lamp, how long did it go from zero to hero? And can it hold the charge now?
